The perfect stranger : a novel

"A journalist sets out to find a missing friend, a friend who may never have existed at all. Confronted by a restraining order and the threat of a lawsuit, failed journalist Leah Stevens needs to get out of Boston when she runs into an old friend, Emmy Grey, who has just left a troubled relationship. Emmy proposes they move to rural Pennsylvania, where Leah can get a teaching position and both women can start again. But their new start is threatened when a woman with an eerie resemblance to Leah is assaulted by the lake, and Emmy disappears days later. Determined to find Emmy, Leah cooperates with Kyle Donovan, a handsome young police officer on the case. As they investigate her friend's life for clues, Leah begins to wonder: did she ever really know Emmy at all?"-- Provided by publisher.
