The girl just looked at her for a second, as if she didn't understand what she was saying. Which, with Clarke's congestion, she probably didn't. I leaned over and picked up the bag, holding it out to her. "You left this," I said.

She looked at the bag, then up at me, her expression guarded. "Oh," she said, reaching for it. "Thanks."

Behind us, a bunch of kids coasted past on their bikes, their voices loud as they called out to one another. Then it was quiet again.

"Honey?" I heard a voice call out from the end of the dark hallway behind her. "Is someone there?"

"It's okay," she said over her shoulder. Then she stepped forward, shutting the door behind her, and came out onto the porch. She quickly moved past us, but not before I saw that her eyes were red and swollen—she'd been crying. And suddenly, like so many other times, I heard my mother's voice in my head: Moving to a new place is tough. Maybe she doesn't know how to make friends.

"Look," I said, "about what happened. My sister—"

"It's fine," she said, cutting me off. "I'm fine." But as she said it, her voice cracked, just slightly, and she turned her back to us, putting a hand to her mouth. I just stood there, totally unsure what to do, but as I looked at Clarke, I saw she was already digging into the pocket of her shorts to pull out her ever-present pack of Kleenex. She drew one out, then reached around the girl, offering it to her. A second later, the girl took it, silently, and pressed it to her face.

"I'm Clarke," Clarke said. "And this is Annabel." In the years to come, it would be this moment that I always came back to. Me and Clarke, in the summer after our sixth-grade year, standing there behind that girl's turned back. So much might have been different for me, for all of us, if something else had happened right then. At the time, though, it was like so many other moments, fleeting and unimportant, as she turned around, now not crying—surprisingly composed, actually—to face us. "Hi," she said. "I'm Sophie."

Chapter Two

"Sophie!"

Finally it was lunchtime, which meant that this, the first day of school, was now at least half over. All around me, the hallway was packed and noisy, but even with locker doors clanging and the droning of various announcements from the intercom, I could still hear Emily Shuster's voice, clear as day.

I looked down the hall to the main staircase and sure enough, she was coming toward me, her red head bobbing through the crowd. When she finally emerged about two feet from where I was standing, our eyes met, but only fleetingly. Then she was quickly moving on, down the hall to where Sophie was waiting for her.

Since Emily had been my friend first, I'd thought maybe, just maybe, she might still be. Apparently not. The lines had been drawn, and now I knew for sure I was standing outside of them.

I had other friends, of course. People I knew from my classes, and from the Lakeview Models, which I'd been doing for years now. It was becoming clear, though, that my self-imposed isolation during the summer had been more effective than I'd realized. Right after everything happened, I'd cut myself off entirely, figuring this was safer than risking people judging me. I blew off phone calls and avoided people when I saw them out at the mall or the movies. I didn't want to talk about what had happened, so it seemed safest not to talk at all. The result, however, was that now all morning, when I'd stopped to say hello to girls I knew, or walked up to groups of people chatting, I'd felt an instant coolness and distance, one that lingered until I made my excuses and walked away. Back in May, all I'd I wanted was to be alone. Now I'd gotten my wish.

My association with Sophie didn't help, of course. Hanging out with her made me a party to all her various social crimes and misdemeanors—and there were many—so there was a wide portion of the student body that was not exactly rushing to embrace me. To the girls Sophie had insulted and isolated while I stood by doing nothing, my own taste of this medicine was nothing short of deserved. If Sophie couldn't be ostracized, I was the next best thing.

Now I headed down to the main lobby, stopping in front of the long row of glass doors that looked out over the courtyard. Outside, the various cliques—jocks, art girls, pols, burnouts— were scattered across the grassy spaces and walkways. Everyone had a place, and once I'd known mine: the long wooden bench to the right of the main walkway, where Sophie and Emily were sitting. Now I was wondering if I should even go out at all.

"It's that time of year again," someone called out in a falsetto voice from behind me. There was a burst of laughter, and as I turned around, I saw a group of football players hanging out by the front office. A tall guy with dreadlocks was imitating the way I'd held out my arm to that guy in the commercial, while the rest of them snickered. I knew they were just goofing around, and maybe another time it wouldn't have bothered me. But now, I felt my face flush as I pushed the doors open in front of me and stepped outside.

There was a long wall to my right, so I headed toward it, looking for a spot, any spot, to sit down. There were only two people sitting on it, the distance between them just big enough to make it clear they weren't together. One was Clarke Reynolds. The other was Owen Armstrong. It wasn't like I had a lot of choices of seating or company, so I sat down between them.

The bricks were warm on my bare legs as I busied myself pulling out the lunch my mother had packed for me that morning: open-faced turkey sandwich, bottled water, and a nectarine. I uncapped the water, taking a big sip, before I finally allowed myself to take a look around. As soon as I glanced over at the bench, I saw Sophie was watching me. When our eyes met, she smiled a thin-lipped smile, shaking her head before looking away.
