It’s the start of the school year, and the popular girls have decided to throw the best party, one their friends will never forget. But hooking up and hanging out are the farthest things from their minds when the unthinkable happens: Someone doesn't make it out of the party alive.

The death is declared a suicide, but nothing quite adds up. Convinced there’s a murderer on the loose, no one knows who they can turn to or who they can trust. Nowhere is safe, not the homecoming dance, not even graduation.

The truth will terrify them, but it must be revealed. Their lives depend on it
