A young man will go to any length to uncover the truth about his girlfriend's death in this "expertly crafted, psychologically ambitious" thriller (Publishers Weekly, starred review). Jarlath "Jar" Costello never got over his girlfriend's suicide five years ago. In fact, he's certain she's still alive. The brilliant young Cambridge student was crushed by the loss of her father. It's said that she leapt to her death off the cliffs of Norfolk. The case is closed . . . though her body was never found. Jar still sees Rosa everywhere—a face on the train, a figure on the cliff. He wonders if he might be going mad. Then he gets an imploring email: "Find me, Jar. Find me, before they do. . . ." As Jar digs into the past, he enters a dark underworld where nothing is as it seems, and no one can be trusted. He is soon thrust into the heart of a larger intrigue that may finally shed some light on Rosa's death . . . even as it dangerously threatens his own life.
