Twin sisters Marisa and Clare Stockton were sixteen when Clare's body was found in Virginia's James River. No arrests were made. Fourteen years later, Marisa's friends and dedicated career as a photographer help her to cope with the open wound of the past. But Marisa still feels the hurt - and the unsolved murder isn't the only thing haunting her.

A recent car crash has erased ten days of Marisa's memories - a black hole leading up to the accident that's left her disoriented. Every text and phone call from that crucial missing time has vanished, along with her phone. A photograph she took of the river has disappeared. A new neighbour Marisa believes she knows introduces himself as if he were a stranger. And there's the growing fear that her near-fatal accident was no accident at all. As dreams of Clare and nightmares of the crash begin to converge, so do two disturbing puzzles fourteen years apart.

Putting the pieces together could be fatal. As she struggles to remember everything, Marisa closes in on a killer- without realising that he's already closed in on her.
