Tristan Castilion, a celebrated Commander of the Vampire Royal Guard, just wanted to be left alone. He wanted nothing to do with the war brewing among all the supernaturals and had grown tired of fighting all these centuries. All of them were screwed up anyway; but who was he to judge who drinks blood and who eats souls? 

Sucked into one last mission from his vampire government, Tristan soon finds himself in the middle of a dark conspiracy within the vampire ranks and a half-naked demon chained to his bed.

And not just any old demon…
Zoe is a Black Blood Slayer—legendary demons bred to do one thing: kill vampires. A true ruler of the night, she's forced to keep her lethal wiles at bay in order to uncover the truth, creating an unlikely partnership with Tristan.

Her blood is spiked with a desire he longs to tame, but if he does, he could be six-feet under; this time forever. But with both of them on the run and all hell breaking loose, how can he be sure she wants him to love or to destroy?
