Two families come to terms with a devastating tragedy. Arden and Rory Falcone have always considered themselves more like sisters than cousins, even opting to room together when they leave for the same college. A few weeks into their first semester, a fire destroys the girls' dorm room, killing Rory's boyfriend, Hunter, and leaving both girls in critical condition. As Rory and Arden fight for survival, their stories unfold, and secrets emerge about the cousins' relationships with their families, their peers, Hunter, and, of course, each other. But the secret of how the fire started is the one weighing most heavily.
