Fifteen years ago in Boston, Kate Summers made a bargain: she became the mother of a perfect, beautiful newborn baby, and she promised she would never breathe a word about the adoption to anyone.

Now Kate has built a good life for herself and her son, Jon, in a small town in Oregon. She has almost forgotten her fear that he will somehow be taken away.

Then Daegan O'Rourke arrives in town and strikes up a friendship with her and Jon. Daegan has his own past to hide - one with shocking ties to hers.

Someone is searching for Kate and her son and is willing to go to any lengths to claim him. And the one man Kate is tempted to trust has dangerous secrets that could change her world forever.

Soon, the past Kate thought she could outrun will explode, unearthing a legacy of lies and treachery and a fury powerful enough to kill.
