Five years ago, Rosa walked to the pier in the dead of night, looked into the swirling water and jumped. She was a brilliant young Cambridge student who had just lost her father. Her death was tragic, but not unexpected. Her death was ruled a suicide. But Rosa’s boyfriend, Jar, still can’t let go. He sees Rosa everywhere—a face on the train, a figure on the cliff. He is obsessed with proving that she is still alive. And then he gets an email. 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.
