Moonsick -- Tom O'Donnell, Hardcover

Scream meets Stephen King in this fast paced debut YA horror novel about a girl trying to survive a world where becoming a werewolf is a contagious disease.

High school senior Heidi Mills seemingly has it all: a charming (arrogant) boyfriend, loving (wealthy) parents, and an acceptance letter to Harvard (well, not yet). With her mom and stepdad away on vacation, she's going to host a rager at their mansion to celebrate the end of high school.

The party is tomorrow. But the full moon is tonight--when the worldwide werewolf epidemic that has run rampant for the past few years turns deadly, and the infected transform into beasts.

Safe in her home, with its state-of-the-art lockdown system to keep the monsters out, Heidi expects to wait out the night. But when two intruders show up to rob what they think will be an empty home, the life of privilege, ease, and safety that Heidi has taken for granted comes crashing down. Suddenly exposed to the realities of this virus and the way that the rest of the world has been living all this time, Heidi embarks on a dark adventure accompanied by the mysterious--but intriguing--boy who broke into her house. As she fights to survive the underbelly of a post-pandemic society, she'll learn that not all monsters have fangs.

With flourishes of Wes Craven and The Purge, this comedic horror novel is perfect for fans Grady Hendrix, Adam Cesare, and things that go bump in the night.
