Twenty-five years of quiet solitude shatter when Michael Valerius awakens to a terrifying truth: he is the Tribrid, a being born of vampire, lycan, and witch, destined to either rule or destroy all three worlds. As ancient powers ignite within him, a deadly assassin, Seraphina Draven, arrives with orders to end his life. But when their touch ignites an undeniable, violent mating bond, their fated collision becomes a desperate hunt. Sera, bound to the very king who murdered Michael's parents, is torn between duty and a primal connection she can't escape. Can she betray her master and embrace a destiny she never wanted, or will the Tribrid's awakening plunge all realms into an eternal eclipse?
