When the demons arrive, not even The Society can escape extinction.

Soft-spoken and sharply dressed, William, a bitten vampyr, has sworn his loyalty to The Society--and when an imminent demon invasion threatens everything his family has worked so hard to build, he quickly comes up with a plan to save them all. But he'll need Evan, a stunning and defiant woman, to help rally what's left of humanity…

Evan is the last human who wants to see the Vampires saved. But with the demons set to destroy all life on earth--human and Vampire alike--she'll have to partner with William to survive. Yet the dangerous twists and turns ahead only bring the two closer, uncovering forbidden desires neither dreamed were possible. Will their newfound romance be enough to conquer a centuries-long feud? Or will it put the entire world at risk?
