You wonder what this book's about. You examine the front cover. You open it up and look at the page or screen. You start reading.

         "Come on, Professor Carsen. Go ahead and try it," my research assistant Emily said as she handed me the Virtual Reality Immersion gear. It consisted of a big black helmet with a lot of wires coming out of it. We'd connected to a special quantum computer which Emily had created under my direction. We sat in my lab surrounded by computers and other equipment at the university. Yes, it was a little messy with all the gear piled up but I'd worked for years to accumulate it via research grants. I wasn't about to part with any of it.
         For some reason, now I was getting cold feet. We'd been working on this new quantum experiment for months and now we were finally ready to go. The experiment needed a human's consciousness so I needed to put on the helmet and connect to it.
         I took the helmet but didn't put it on.
         "What's wrong, Chloe?" she asked, not looking nervous at all. Of course, she'd done VR before, loads of times. Her roommate was a VR expert and worked for a VR company.
         Oh, yeah, and her experiment and her research grant weren't on the line.
         "I guess I'm nervous." I turned the helmet upside down and peered inside. It looked a lot like a motorcycle helmet. I wasn't nervous about VR. I was nervous that I'd find out all my hard work had been for nothing. What if my hypothesis was wrong? What if I put on the helmet and didn't see anything?
         "I thought you had to get your brain waves into the program so you could look for parallel universes?"
         "I do." According to quantum mechanics, human consciousness plays a special role in the universes. I hypothesized I could use this specialness along with quantum entanglement to hone in on consciousnesses in parallel universes. I knew it was kind of a freaky idea, but I had some elegant and well-received mathematics that backed me up.
         It was time to walk the walk instead of just talking the talk.
         She reached for the helmet. "Well, I'll do it if you want. I want to find another world. It sounds fun."
         "No. I'll do it." I paused.
         "Sometime soon?" She smiled.
         "I'm doing it. Here I go." I carefully placed the Immersion helmet over my head. It felt like a motorcycle helmet, but smelled mildly of plastic and chemicals. Disoriented, I swayed a little.
         "Maybe you should sit down." Emily took my hand and led me to a lab stool. "There. Are you okay?"
         It was very dark. All I could see were a bunch of pinprick LED lights in shades of red, green, yellow, and white. "Yeah. I guess."
         "Can you get to the menu?"
         I wasn't familiar with the VR technology even though it wasn't new. "Remind me about the VR menu." Even to me my voice sounded muffled.
         "You blink to control access."
         "Right." I knew that. I blinked deliberately and the access menu floated in front of my face. I blinked some more and, poof, the menu disappeared. "Ack."
         "What happened?" she asked. "I couldn't hear what you said."
         "Nothing." I blinked again slowly and the menu reappeared. I blinked more quickly to scroll down the left column. When I got to VR Immersion I blinked deliberately again.
         Suddenly, I was falling. I groped around for something to steady me. My hands hit the edge of a lab table and I grabbed on.
         "Professor Carsen?" Emily's voice seemed to come from a great distance. "Chloe?"
         I saw something blurry in front of me. As I tried to focus in on it, my sense of the lab with its stool and table and special computer faded away.
         The blurry something was bluish. I saw a blue-gray something. What was it? I leaned forward, staring. It moved. It sort of waved, like the surface of the earth during an earthquake--or like the ocean. That's what it was: water.
         I jerked back. Why was I seeing water? What did it mean? Could it be another world?
         "Chloe?"
         But there was no ocean around here. According to the theory, my mind should entangle with the mind of another version of me. I should see, or maybe even experience, what she saw or experienced. It was hard to fathom why I'd be seeing an ocean.
         "Are you all right?" Emily's voice seemed louder.
         Something was wrong. I blinked deliberately and the menu popped back up. I blinked my way out and tore off the helmet. I breathed in the fresh air greedily.
         "What happened?" Emily leaned over me, looking concerned.
         "I don't know." I shook my head. "On the bright side, I saw something." That was bright. It was incandescent.
         "Yeah!" she said. I agreed.
         "On the dark side, I think I saw the ocean."
         "The ocean?" she said. "That's weird. I thought you said you'd probably see Montana in another universe. There's no ocean in Montana."
         "I know that."
         "Could there maybe be an ocean in Montana in some other universe?" she asked slowly.
         "No." I paused. Could there be? "No. I don't see how."
         "Are you sure?"
         "The elevation alone would make it impossible."
         "But Montana wasn't always at this elevation. . ."
         "It has been for, like, the last eighty million years."
         "Could the time be off somehow?"
         "Not eighty million years off. And the brain waves over there have to be similar enough to entangle with mine. I don't see how that could happen millions of years ago." Damn. It must not have worked. I must not have seen another world. What did I see then?
         She backed away. "Okay. I'm just asking." Her phone pinged and she glanced at it. "Shoot. I have to go. I'm supposed to meet some friends to study."
         "Go ahead. I need to ponder things." I forced a smile. "Thanks for your help. I appreciate it."
         "You're welcome." She grabbed her backpack. "I don't think you should try the helmet again without me. You seemed pretty dizzy or something."
         "Thanks for the advice."
         "If not me, someone else," she said, reading in my tone that I wasn't going to take her advice. "What about your brother, Dr. Carsen? He seems to stop by the lab a lot."
         When he wasn't away working for the National Guard, Colton worked here on campus at the health center as a physician. He didn't stop by a lot. He stopped by once in a while when we went to lunch.
         I stood. "Okay. Thanks a lot, Emily." I led her to the door. "You don't want to be late for your study session. And I have a lot of work to do. I need to double-check everything."
         She left and I went over to the computer.
         I doubled-checked everything, but I couldn't find anything wrong with our physical equipment setup or our special computer. And several other physicists had checked my math so my hypothesis was sound.
         I decided to try the VR helmet again. I dragged a more comfortable chair into the lab from my office first though, and sat in it before I put on the helmet.
         I blinked slowly and the menu appeared. I blinked more quickly to scroll down the left column. When I got to VR Immersion I blinked deliberately again. I was getting the hang of this.
         I saw something blurry in front of me. I saw blue-gray waves. I focused. As I scrutinized it, my sense of the lab went away.
         I saw waves. I smelled something chemical. I sniffed. Chlorine, maybe. And then I saw concrete. A pool. I was looking at a pool. That made much more sense. There were several pools in town.
         I focused and got a sense of someone by a pool. . .

         The Harry Potters started arriving at two p.m. It was amazing how similar they all looked with drawn-on scars, round plastic glasses, and capes.
          My oldest son, Zach, rolled his eyes as each one passed him at the neighborhood clubhouse entrance. Rolling your eyes was apparently a big brother requirement--at least at birthday parties for little brothers.
          Several of the parents greeted me as they dropped off their sons.
         Chris's father, Nick, stopped near the door. "Hi, Chloe." I got a whiff of his lavender-scented aftershave.
          I nodded. "Hi, Nick." I grinned back at him. If memory served, this guy was also our state representative, so it didn't hurt to be friendly.
         "What time should I pick Chris up?" he asked. Chris had long since scampered off to join the rest of the boys.
          "Six-ish," I said.
          "Hey, Nick." My husband Aidan touched the small of my back.
          Nick waved back at him.
          "So, we'll see you at six," I said.
          Nick nodded and departed.
          "I'm going to go pay the manager the rental fee," Aidan said. We'd rented out the house-sized empty building for the afternoon. "Can you hold down the fort?"
          I smiled. I loved having a househusband. He was so good at taking care of details. "Considering only a few kids are here so far, and I have Zach to help, I think we'll be fine."
          He nodded and headed for the manager with the checkbook.
          I walked over to Zach. "Thanks for your help with the party," I said. He'd helped set up the various folding tables and chairs, put up the Happy Birthday banner and placed latex helium balloons around this main room. "I know your brother appreciates it."
          "Whatever, Mom." He smirked. It seemed like that was his go-to expression these days.
          We both looked at Trevor who, as birthday boy, was already lording it over the other boys, telling them where to put their gifts, and showing them where the snacks were.
          I saw the ghost of a grin flit over Zach's face before he noticed me noticing. "I guess the little squirt only turns double-digits once." Zach couldn't fool me. I knew he had a soft spot for the little squirt. I suppressed my own grin.
          Once all the Harrys arrived, they ate. Trevor had requested hot dogs, string cheese, grapes and pretzels. After that we did N.E.W.T. exams in Divination where they studied tea leaves and made stuff up, Care of Magical Creatures where they identified imaginary creatures on cards and explained how to take care of them, Defense Against the Dark Arts which involved goofing around with fake light sabers, and Astronomy.
          I couldn't resist teaching them some real Astronomy during the Astronomy N.E.W.T. So sue me, I'm a physics professor. I'm sure if it hadn't been dark in the clubhouse I would have seen Zach rolling his eyes the whole time. I'd brought my true-to-life star map painted in glow-in-the-dark paint and put it up on one of the walls.
          I was pointing out constellations with the laser pointer. "So, here's Cassiopeia, which looks like a chair, see?" I said. "She's supposed to be Andromeda's Mother, or some people say she's the Queen of Ethiopia. And here's Ursa Major which contains the most famous constellation, the Big Dipper. Has anyone ever seen the Big Dipper before?" I asked.
          A chorus of me's and I have's erupted from the crowd.
          "Excellent," I said. "I'm glad to hear it. The name Ursa Major means the Great Bear, and it points at the North Star, Polaris. What's your favorite constellation, Trevor?"
          Trevor said, "Orion. With the belt."
          "Can you show it to us?" I asked.
          Trevor jumped out of his chair and lunged for the map.
          In the meantime, Aidan was getting the cake ready with Zach's help in the kitchenette. Zach manned the flashlight as Aidan lit the birthday candles.
          I was keeping an eye out for the lit candles, so as soon as they appeared I said, "And now I think it's time for what we've all been waiting for, birthday cake. Come on." The little flames on the cake lit up the whole room.
         Everyone ran over to the table, and we sang Happy Birthday.
          Trevor looked at his friends and family and beamed in the candlelight.
          "Come on, buddy," Aidan said. "Make a wish and blow out the candles."
          Trevor paused a moment and then blew the candles out. The boys cheered and at the same time, wind blew the doors of the clubhouse open. I went and closed them.
          Zach flipped on the lights and said, "What'd you wish?"
          Trevor just smiled mysteriously. He knew you weren't supposed to reveal your wish if you wanted it to come true.
          Aidan started cutting the cake. He'd made it from scratch. It was dark chocolate cake with fudge chocolate frosting and milk- and semi-sweet chocolate chips throughout--basically death by chocolate. I could only eat about a cubic centimeter of the stuff. It smelled heavenly, however. Probably just breathing it in was fattening.
          We handed out small pieces of cake to everyone. With the party excitement the last thing we needed was an upset stomach--or worse.
          By the time everyone had their piece, the birthday boy was already asking for more. "Come on, Mom," Trevor said. "Give me another piece. It's my birthday. I'm double-digits, now."
          "Nope," I said. "Sorry, buddy. Not going to happen. You'll get sick. You can have a piece tomorrow."
          He gave me a stony look that I knew meant he wasn't happy with me.
          I crossed my arms and gave him my I'm not backing down look. I was as firm as Corundum.
          He scowled and grabbed his magic wand, mumbling and waving it at his plate. Then, as if by magic, another piece of cake appeared on his formerly empty plate.
          "What the f--?" Zach started to say.
          He was saying what I was thinking. What just happened?
          I interrupted him, "Zach, don't say that. Aidan. Come over here, please. Did you see this?" I pointed at Trevor's plate.
          Aidan had been rolling up the star map, but put it down and walked our way.
          Trevor smiled widely and said, "It worked. I made cake. My magic wand works!"
         The other boys crowded around him. "Cool!" "Awesome!" "Neat!"
          My mind was reeling. There was no such thing as magic--at least that's what I thought.
          Immediately, the boys started waving their wands around but no more pieces of cake magically appeared.
          Zach grabbed Trevor's wand out of his hand and rotated it, staring.
          "You better give that back," Trevor said.
         "I will, in a minute, squirt," Zach said.
          Maybe I'd imagined the extra piece of cake on Trevor's plate?
          Aidan approached the table and asked, "What's going on?"
          "I'm not sure," I said.
          Trevor wasted no time in shoving the extra piece of cake into his mouth.
          The other boys were still eating their first pieces of cake.
          Aidan whispered into my ear, "What might have happened?"
          I whispered back to him, "It almost seemed like Trevor did magic to get another piece of cake."
          "Wow. That would be great," he said, grinning. "I'd love to have a magic son." Aidan was definitely a native son of Missoula Montana. There wasn't a yoga position he couldn't do, granola he wouldn't eat, or a weird idea he wouldn't consider.
          I didn't know what to think.
          The rest of the party occurred without any further mysterious incidents.
          After the guests (exhausted) had gone and we were packing up, Trevor asked, "When can I get my wand back? I want to do magic."
          I'd taken it from Zach and put it in my back pocket.
          "I like magic," Aidan said. "If Trevor can do tricks, I'd like to see them."
          Zach was shaking his head and scowling.
          "Can I?" Trevor asked. "Can I, Mom?"
          I had to admit I was very curious about what'd happened. I handed the wand over. "Sure, little dude. Knock yourself out."
          Trevor eagerly took the wand back from me.
          "Wait," Zach said. "What are you going to do?"
          "I'm going to get another piece of cake." He stared down at an empty paper plate.
          While they were all looking at Trevor's plate, I stared at the remnants of the birthday cake still on the table. The seemingly-magic piece of cake earlier couldn't have materialized out of thin air.
          "Abra Cadabra!" Trevor said. "Make-uh the cake-uh!" He waved his wand around.
          "No way," Zach said.
          "Wow." Aidan sounded surprised.
          A piece of the birthday cake had disappeared from the serving platter. Wow, was right. I glanced at Trevor's plate. There it was.
          "Hey, let me try," Zach said, reaching for the wand.
          "No. It's my party." Trevor clutched the wand to himself. "I get to do magic. Not you."
          "I'm trying anyway." Zach picked up a paper plate and waved his hand around. "Abra Cadabra! Make-uh the cake-uh!" A piece of cake appeared. He paused for a second and then said, "No effing way! It worked even without the wand."
          "Wow," Aidan said. "And language, young man."
          I glanced at the larger cake still on the platter. I thought another piece was missing. I didn't want to believe it, but the evidence was right in front of my eyes. Somehow my boys moved pieces of cake from the platter to their plates without touching them. "Huh."
          "No fair," Trevor said. "It was supposed to be my magic."
          "Can anyone do it?" Aidan asked. He grabbed his own plate. "Abra Cadabra. Make-uh the cake-uh." He waved his hands.
          The cake on the table looked the same. I glanced at Aidan's plate. It was empty.
          "Darn," Aidan said. "Didn't work."
          "You can use my wand if you want, Dad," Trevor said.
          "Thanks, buddy." Aidan took the wand from Trevor and tried again, but nothing happened. "I guess it's not the wand."
          "You try, Mom," Zach said.
          I was in favor of empirical data. I grabbed an empty paper plate. "Abra Cadabra. Make-uh the cake-uh." Bam. There was a piece of cake on the plate. I almost dropped the plate in my surprise.
          "Wow," Aidan said.
          "Awesome!" Zach said.
          Trevor frowned. "Why can you guys do it?"
          "What do you mean, Trev?" Aidan asked.
          "It was my wish," Trevor said. "I wished I could do magic when I blew the candles out."
          We all digested that for a moment. It was impossible for his birthday wish to come true, right?
          "It must not be your wish, buddy," Zach said. "It must be something else."
          "Can you guys do any non-cake related tricks?" Aidan asked.
          I was still staring at the piece of cake on my plate. It looked like a regular piece of delicious chocolate cake. It was impossible, wasn't it?
          "Abra Cadabra!" Trevor said. "I want an X-box!" Nothing happened. "Darn."
          "Abra Cadabra!" Zach said. "Make-uh the sports car!" Nothing happened. The boys continued trying to do magic, but nothing seemed to be working.
          Aidan sidled up to me. "Are you okay, Chloe?" he asked softly.
          I held out the plate. "There's a piece of cake here."
          He smiled and nodded. "Yes."
          "There didn't use to be."
          "Yes, that's true."
          "Wow." I felt weird. Was this what a paradigm shift felt like?
          "I agree," Aidan said. "Wow."
          "Ahem." Someone cleared his or her throat from the direction of the door. We all turned and saw Chris and Nick standing there. "We just wanted to come in and say thanks," Nick said. How long had they been standing there? What did they see?
         Aidan rushed over to them. "Yes, thanks for coming." He ushered them out through the open door.
          We eventually got everything rounded up and we headed out.
          After we got home from the party and put everything away and convinced the boys that yes, double-digit young men did still have bedtimes, Aidan and I collapsed in the master suite.
          "What happened at the party? How did you guys get extra cake?" Aidan asked, getting into bed.
          I shook my head as I slipped between the cool sheets; they felt smooth and relaxing against my skin. "I don't know. Were we in some kind of sugar coma? Or could Zach have pranked us?"
          "He's good at practical jokes, but he's not that good," he said.
          "I don't claim to know everything," I said. "But I didn't think magic was real." It went against everything I knew, all the physics I'd studied for the last fifteen years.
          "Well, I've always said you've put a spell on me." He nuzzled my neck. "Maybe magic is real."
          I shivered.

         I was yanked out of my life.
         Somehow I was lying in a plush chair in a lab. My neck hurt.
         Emily and Colton were leaning over me, glaring.
         "Are you all right?" Emily asked.
         I was just with my family, my husband Aidan and sons Zach and Trevor. It was lovely.
         "I'm concerned," Colton said. "Should I call 911?"
         But I didn't have a family. Aidan and Zach and Trevor didn't exist. What just happened?
         "Chloe!" Colton put his face right in my face. "Answer me."
         I was so confused. I looked at Colton. He held a black helmet in his hand. I looked at Emily. They both seemed upset.
         I glanced around the room, my lab. I did know this lab. I did know these people. Oh, yeah, this was my life. So, where had I just been?
         "Chloe," Colton said.
         "I'm okay," I said. "Just disoriented."
         "I'll say," he said.
         "How long were you in there?" Emily asked.
         "In where?" Oh, right, I was doing an experiment. "I don't know," I said. "What time is it?"
         "It's late, almost eleven," Colton said.
         "At night?" I asked.
          "Yes, at night," he said. "What's wrong with you?"
         "Chloe, have you been here all day?" Emily turned to Colton. "Maybe you should call 911."
         "No, I'm fine." I sat up. My back creaked. "I just lost track of time."
         "Were you in the experiment this whole time?" she asked.
         "I guess so," I said. My fuzzy brain was clearing. I jumped up. "I think it works!"
         "What?" they both asked.
         "I think I accessed a parallel world. Oh, wow. It works." This was the greatest moment of my life. "This is huge!" I wanted to get right back into the experiment, it was so exciting.
         "It works?" Emily beamed and hopped in excitement. "Wow. What's it like?"
         "What works?" Colton asked, his nose wrinkled.
         "My," I glanced at Emily, "our, experiment works. I accessed another world. I explained this to you before, Colton."
         "Yeah," he said. "I never understood what you were talking about."
         "Well, the point is, it works. It didn't feel the way I thought it would though. It seemed real." I touched Colton's arm. He was real. This was real. Here. Now. I had to check.
         That other place wasn't real like this was real. But it seemed so real. At the time, it seemed as real as this.
         I wanted to go back there. I rubbed my neck.
         "What did you see?" Emily asked.
         "It wasn't like seeing," I said. "It was like being. It was like I was there, me, Chloe. I had a whole other life."
         "What the hell, Sis?" Colton said.
         "I don't know how to explain it." I stretched my back.
         "Cool!" Emily said. "Can I try it?"
         I didn't want to surrender the equipment to her.
         "It sounds dangerous," Colton said. "I don't think you should do it again."
         I just looked at him, not answering.
         They didn't understand.
         I had to do it again.
