On a hot summer night, Liv, Morgan, Clay and Nathan are on the way home from a party in Clay's convertible. Best friends dating brothers? It doesn't get better than that. But the joyride ends in sudden impact, a screech of brakes, and shattering glass. On that lonely country road, four lives change forever.

Liv wakes in the hospital. At first she's confused when they call her Morgan, but she assumes it's a case of mistaken identity. Yet when the bandages come off, it's not her face inthe mirror anymore. It's Morgan's.

Morgan always seemed to have the perfect life. But as Liv tries to fit herself into Morgan's world, she discovers endlessly disturbing secrets of the criminal and murderous variety and a dark task to finish...if she doesn't lose her mind first.

Forced to confront the disturbing truths that Morgan kept hidden in life, Liv must navigate a world of long-buried murder, a dangerous love affair—and a romance that feels like a betrayal.
