The Countdown Club (Paperback)
Rayna Butler is an art geek, but even her Kool-Aid dyed hair and her edgy paintings don't make her stand out much from the crowd. So when she arrives at school one Monday morning and finds a note in her backpack that reads "Six Days to Die," she's sure that it's just a prank.
Jack Harkness is one of the toughest guys in school, a loner hiding his painful home life. When he receives one of the threatening notes he doesn't take it for anything he can't handle.
But others have received threatening notes, each with a different expiration date. "Six Days to Die"... "Two Days to Die"... "Twelve Days to Die"... there's no rhyme or reason to it. And none of the kids appear to have anything in common.
The students don't know how seriously to take the threats-until the first murder. Liam, the class salutatorian, is the first to go, when his house mysteriously burns down around him. Certain that their days are numbered, Rayna and Jack convince the others to join together to track down the killer before their time is up.
