I went through each desk in the office again, but it seemed more and more obvious that Margo had used only the desk with the nail polish in the drawer and the calendar set to June.

I ducked through a Troll Hole and made my way back to the library, walking again through the abandoned metal shelves. On each shelf I looked for dustless shapes that would tell me Margo had used this space for something, but I couldn’t find any. But then my darting flashlight happened across something atop the shelf in a corner of the room, right near the boarded-up storefront window. It was the spine of a book.

The book was called Roadside America: Your Travel Guide, and had been published in 1998, afterthis place had been abandoned. I flipped through it with the flashlight crooked between neck and shoulder. The book listed hundreds of attractions you could visit, from the world’s largest ball of twine in Darwin, Minnesota, to the world’s largest ball of stamps in Omaha, Nebraska. Someone had folded down the corners of several seemingly random pages. The book wasn’t too dusty. Maybe SeaWorld was only the first stop on some kind of whirlwind adventure. Yes. That made sense. That was Margo. She found out about this place somehow, came here to gather her supplies, spent a night or two, and then hit the road. I could imagine her pinballing among tourist traps.

As the last light fled from the holes in the ceiling, I found more books above other bookshelves. The Rough Guide to Nepal; The Great Sights of Canada; America by Car; Fodor’s Guide to the Bahamas; Let’s Go Bhutan. There seemed to be no connection at all among the books, except that they were all about traveling and had all been published after the minimall was abandoned. I tucked the Maglite under my chin, scooped up the books into a stack that extended from my waist to my chest, and carried them into the empty room I was now imagining as the bedroom.

So it turned out that I did spend prom night with Margo, just not quite as I’d dreamed. Instead of busting into prom together, I sat against her rolled-up carpet with her ratty blanket draped over my knees, alternately reading travel guides by flashlight and sitting still in the dark as the cicadas hummed above and around me.

Maybe she had sat here in the cacophonous darkness and felt some kind of desperation take her over, and maybe she found it impossible to unthink the thought of death. I could imagine that, of course.

But I could also imagine this: Margo picking these books up at various garage sales, buying every travel guide she could get her hands on for a quarter or less. And then coming here — even before she disappeared — to read the books away from prying eyes. Reading them, trying to decide on destinations. Yes. She would stay on the road and in hiding, a balloon floating through the sky, eating up hundreds of miles a day with the help of a perpetual tailwind. And in this imagining, she was alive. Had she brought me here to give me the clues to piece together an itinerary? Maybe. Of course I was nowhere near an itinerary. Judging from the books, she could be in Jamaica or Namibia, Topeka or Beijing. But I had only just begun to look.

In my dream, her head was on my shoulder as I lay on my back, only the corner of carpet between us and the concrete floor. Her arm was around my rib cage. We were just lying there, sleeping.

God help me. The only teenaged guy in America who dreams of sleeping with girls, and justsleeping with them. And then my phone rang. It took two more rings before my fumbling hands found the phone lying on the unrolled carpet. It was 3:18 A.M. Ben was calling.

“Good morning, Ben,” I said.

“YESSS!!!!!” he answered, screaming, and I could tell right away that now was not the time to try to explain to him all I had learned and imagined about Margo. I could damn near smell the booze on his breath. That one word, in the way it was shouted, contained more exclamation points than anything Ben had ever said to me in his entire life.

“I take it prom is going well?”

“YESSSS! Quentin Jacobsen! The Q! America’s greatest Quentin! Yes!” His voice got distant then but I could still hear him. “Everybody, hey, shut up, hold on, shut up — QUENTIN! JACOBSEN! IS INSIDE MY PHONE!” There was a cheer then, and Ben’s voice returned. “Yes, Quentin! Yes! Bro, you have got to come over here.”

“Where is here?” I asked.

“Becca’s! Do you know where it is?”

As it happened, I knew precisely where it was. I’d been in her basement. “I know where it is, but it’s the middle of the night, Ben. And I’m in—”

“YESSS!!! You have to come right now. Right now!”

“Ben, there are more important things going on,” I answered.

“DESIGNATED DRIVER!”

“What?”

“You’re my designated driver! Yes! You are so designated! I love that you answered! That’s so awesome! I have to be home by six! And I designate you to get me there! YESSSSSSS!”

“Can’t you just spend the night there?” I asked.

“NOOOO! Booooo. Booo on Quentin. Hey, everybody! Boooo Quentin!” And then I was booed. “Everybody’s drunk. Ben drunk. Lacey drunk. Radar drunk. Nobody drive. Home by six. Promised Mom. Boo, Sleepy Quentin! Yay, Designated Driver! YESSSS!”

I took a long breath. If Margo were going to show up, she would have showed up by three. “I’ll be there in half an hour.”

“YES YES YES YES YES YES YES YES YES YES YES YESSSSSS!!!! YES! YES!”

Ben was still making assertions of affirmation when I hung up the phone. I lay there for a moment, telling myself to get up, and then I did. Still half asleep, I crawled through Troll Holes past the library and into the office, then pulled open the back door and got into the minivan.

I turned in to Becca Arrington’s subdivision just before four. There were dozens of cars parked along both sides of Becca’s street, and I knew there would be more people inside, since many of them had been dropped off via limo. I found a spot a couple cars away from RHAPAW.

I had never seen Ben drunk. In tenth grade, I once drank a bottle of pink “wine” at a band party. It tasted as bad going down as it did coming up. It was Ben who sat with me in Cassie Hiney’s Winnie-the-Pooh — themed bathroom while I projectile-vomited pink liquid all over a painting of Eeyore. I think the experience soured both of us on alcoholic pursuits. Until tonight, anyway.

Now, I knew Ben was going to be drunk. I’d heard him on the phone. No sober person says “yes” that many times per minute. Nonetheless, when I pushed past some people smoking cigarettes on Becca’s front lawn and opened the door to her house, I did not expect to see Jase Worthington and two other baseball players holding a tuxedo-clad Ben upside down above a keg of beer. The spout of the beer keg was in Ben’s mouth, and the entire room was transfixed on him. They were all chanting in unison, “Eighteen, nineteen, twenty,” and for a moment, I thought Ben was getting — like — hazed or something. But no, as he sucked on that beer spout like it was mother’s milk, little trickles of beer spilled from the sides of his mouth, because he was smiling. “Twenty-three, twenty-four, twenty-five,” the people shouted, and you could hear their enthusiasm. Apparently, something remarkable was taking place.

It all seemed so trivial, so embarrassing. It all seemed like paper kids having their paper fun. I made my way through the crowd toward Ben, and was surprised to happen across Radar and Angela.

“What the hell is this?” I asked.

Radar paused from counting and looked over at me. “Yes!” he said. “The Designated Driver cometh! Yes!”

“Why is everyone saying ‘yes’ so much tonight?”

“Good question,” Angela shouted to me. She puffed out her cheeks and sighed. She looked almost as annoyed as I felt.
