The passionate, impulsive Briana Howard and the sly, snarky Jonas Whitmeyer, make a perfect mess of a couple. Both are stubborn, smart and sexy. They're also human clones with supernatural powers.

Jonas had resigned himself to a solitary life on the remote island of Palmyra, home of Sandra Whitmeyer's clandestine clone-growing lab. With young clones now inexplicably dying, Jonas is torn between feeling responsible for cleaning up his mother's mistakes—alone—and his desire to be with Bree.

A heated tussle on Palmyra leaves Jonas and Briana further apart than ever. Bree storms off to Portland, Oregon, but not before encountering clones of a loved one lost long ago.

Jonas tracks down Briana in Portland, where they race to discover the truth about ties between the Howards and the Whitmeyers against a host of obstacles and enemies. Will Jonas and Bree find a way to be together amid an ever-shifting maze of deceit, misdirection and danger unearthed by the darkest of family secrets?
