Leena Thomas's senior year at boarding school starts with a cruel shock: Frost House, the cozy Victorian dorm where she and her best friends chose to live, has been assigned an unexpected roommate - confrontational, eccentric Celeste Lazar.

What Celeste lacks in social grace, however, her brother, David, a recent transfer student, makes up for in good looks and charm. But while he and Leena hit it off immediately, Leena finds herself struggling to balance her growing attraction with her fear of getting hurt.

As classes get under way, strange happenings begin to bedevil Frost House - frames mysteriously falling off walls, doors locking by themselves, furniture toppling over. Celeste blames the housemates, convinced they want to scare her into leaving. And while Leena tries to play peacekeeper between her best friends and new roommate, soon the mysterious happenings in the dorm, an intense triangle between Leena, Celeste, and David, and the reawakening of childhood fears all push Leena to take increasingly desperate measures to feel safe. But does the threat lie with her new roommate, within Leena's own mind . . . or in Frost House itself?

Frost is a stunning and surprising tale of suspense from debut author Marianna Baer.
