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.

When I came to, I was informed by a group of girls that I'm dead. And that because I died under mysterious circumstances, I can't pass straight over to the Other Side. But at least I'm not alone. Meet the Dead Girls Detective Agency: Nancy, Lorna, and Tess—not to mention Edison, the really cute if slightly hostile dead boy. Apparently, the only way out of this limbo is to figure out who killed me, or I'll have to spend eternity playing Nancy Drew. Considering I was fairly invisible in life, who could hate me enough to want me dead? And what if my murderer is someone I never would have suspected?
