What happens when an unstoppable force meets an immovable object in the field of death?

In the dark underbelly of the mob, Tristan Caine has been an anomaly. As the only non-blooded member in the high circle of the Tenebrae Outfit, he is an enigma to all – his skills unparalleled, his morality questionable, and his motives unknown. He is lethal and he knows it.

As does Morana Vitalio, the genius extraordinaire daughter of the rival family. What Caine does with weapons, Morana does with computers. When a twenty-year-old mystery resurfaces, Morana infiltrates Caine’s house, intent on killing him, unaware of a tie that binds them together. Hate, heat, and history clash together with unexpected sparks.

But something bigger, something worse is happening in their world. And despite their animosity, only they can fight it down.
