Tara is gorgeous, affluent, and forty. She lives in an impeccably restored Russian Hill mansion in San Francisco. Once a widow, twice divorced, she's a woman with a past she prefers keeping to herself. Enter Cavin Lattimore. He's handsome, kind, charming, and the surgeon assigned to Tara following a ski accident in Lake Tahoe. In the weeks it takes her to recover, Cavin sweeps her off her feet and their relationship blossoms into something Tara had never imagined possible. But then she begins to notice some strange things: a van parked outside her home at odd times, a break-in, threatening text messages and emails. She also starts to notice cracks in Cavin's seemingly perfect personality, like the suppressed rage his conniving teenage son brings out in him, and the discovery that Cavin hired a detective to investigate her immediately after they met.
