They're good girls . . but no one's perfect . . .

Mackenzie, Ava, Julie, Parker and Caitlin are five senior high-school girls who seem to have it all. Top grades, beautiful looks, music scholarships, sports captaincies... even the boys of their dreams. But there's just one small flaw in their apparently perfect facade. They're wanted for a murder they didn't commit.

Sure, they talked about killing rich bully Nolan Hotchkiss, but they didn't go through with it. It's just a coincidence that Nolan died in exactly the way they planned . . . right? Except Nolan wasn't the only one they fantasised about hurting in film class that day. And now someone seems to have found their list, and is carrying out their very particular revenges in their name.

Who is really behind these killings?

 Who can they truly trust?

 And who will be the next to die?
