Selene Hightower is a killer for hire. A vampire who walks in both the light and the darkness, but lately darkness has a stronger pull. Her unfinished business could cost her the ability to live in the light, throwing her permanently back into the black ink of evil.

Doctor Francesca Swartz led a boring life filled with test tubes, blood trials, and work. One exploratory night, in a world of leather and torture, she is intrigued by a dark and solitary soul. She surrenders to temptation and the desire to experience something new, only to discover that it might alter her life forever.

Will Selene allow the light to win over the darkness threatening the edges of her life? Two women wonder if they can co-exist despite vast differences, as worlds collide and threaten to destroy any hope of happiness. Who will win?
