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?
