From the award-winning author of The Last Getaway comes a thought-provoking story of intrigue and suspense.

Paula Hickman watches the man with whom she shares a dark history move in across the street. Will he unpack their secrets as well?

Stunned to see that the man's new wife is perfectly identical to her, Paula struggles to maintain her sanity, unable to rely on her own perception of events. When a murder rocks their seaside city of Santa Monica, nobody is certain, not even Paula, if she is the killer.

As media attention amplifies and detectives close in, Paula is forced to face both her past and present demons--no easy task when you can no longer trust your own thoughts.
