Seven ancient Vampires Kings. One fight to save humanity… American exchange student Kate Bordessa has fled to Russia to escape her family's hopes that she'll become one of the Proffered—human women who feed and mate with elite vampire warriors, cementing an eons-old alliance.

Grieving over the deaths of his brothers, Vampire Warrior King Nikolai Vasilyev throws himself into battling his ancient enemies, focused only on guilt and vengeance—until the attack that brings him to beautiful, fearless Katya. She gives him a second chance that makes Nikolai want something more for the first time in so long… When their sexual attraction explodes into one night of uncontrolled passion, fate marks them as mates. But is their connection strong enough to convince them to embrace a destiny neither of them wanted?
