Samantha Moore was living a wonderful life with a great fiancée and the perfect job, until she was brutally attacked in a random act of violence. When she woke up after being in a coma for two months, her entire life had changed. Her left leg no longer functioned correctly, and she was haunted by nightmares of the attack. Her family decided to shuttle her off to a lake house in a quiet town away from the busy Twin Cities to recover. But Samantha suspects that this is more to spare them the embarrassment of having a daughter who is no longer The Golden Child who suffered "an accident" (as her mother insists on referring to it).

Her fiancée, Jackson, who is a plastic surgeon, keeps plying her with medication, but Sam doesn't like them as they make her groggy, forgetful, and even more paranoid. Then she discovers that Jackson and her father Lawrence have conspired together to hire Anne Weaver, a physical therapy assistant, to tend to her during the day all summer. Sam resents this, seeing this as the equivalent as being baby-sat all season when she'd rather recover on her schedule.

Sam initially resists Anne's help, despite the fact that she desperately wants to get back to her old life and she can't do that in her current state - hibernating in her room, unable to face other people without panicking, and afraid of going outside. Then Sam begins noticing that some of the things happening aren't only in her head. Why is she having visions of a woman that people on the island are uncomfortable discussing, except in hushed whispers? And why does she know things about this woman even though she has never met her before?

Sam and Anne's characters are well-written, both individually and as a pair that must learn to relate to each other and work together. The development of their relationship is quite organic -- while they eventually reach an understanding, it is not done in a way that seems forced or too cute. The subplot with the rescue dog Roxy was a great touch, as well, as it added depth to Sam's character.

The mystery of the story was excellent. I kept changing my mind as to who was behind the mysterious happenings and why. At one point, I was disappointed that I had "solved" the mystery so early, only to change my mind a few chapters later! While there were plenty of people in the small town who were suspicious, this mystery was crafted quite well, with no heavy-handed red herring.
