Kit looks like your average 17-year-old high school student, but she has a secret: she's London's notorious "Perfect Killer." She chooses who to murder based on letters left in a secret mailbox. Her moral nihilism --- the fact that she doesn't believe in right and wrong --- makes being a serial killer a whole lot easier...until she breaks her own rules by befriending someone she's supposed to murder, as well as the detective in charge of the Perfect Killer case.

Travis Coates has a good head…on someone else’s shoulders. At some point or another, his head got chopped off and shoved into a freezer in Denver, Colorado. Five years later, it was reattached to another guy’s body, and well, here he is. He’s still 16, but everything and everyone around him changed. If the new Travis and the old Travis find a way to exist together, there are going to be a few more scars.
