Maybe if I hadn't slept through my alarm, slammed into Kristin - my high school's reigning mean girl - or stepped in a puddle, destroying my mom's new suede DVF boots (which I borrowed without asking), I wouldn't have been in the wrong place at the wrong time, and I wouldn't have been pushed in front of that arriving train. But I did, and I was. And because I died under mysterious circumstances, I can't pass straight over to the Other Side. Apparently the only way out of this limbo is to figure out who killed me. But at least I'm not alone.
