"I've searched for you so long, my beloved." Katherine is haunted by dreams of past lives. They all have one thing in common: the undying love of a vampire who goes by the name of Mercy. But when Mercy storms into her life, she's nothing like the woman from Katherine's dreams. The terrifying vampire steals everything from Katherine-her family, her friends, even her life when she turns Katherine into a vampire. "This time we'll be together for eternity." Katherine struggles against her undead captor and yet she can't fight the love she feels for Mercy. Is she going insane, or could what Mercy says be true-That Katherine is the reincarnation of Mercy's soulmate, loved and lost four times in eight hundred years? All she knows for certain is that Mercy's obsession will never allow her to let Katherine go. Katherine begins to realize that Mercy is just as much a prisoner of her own love, and begins to wonder, can she find a way to free them both?
