In the shadows of modern-day Caldwell, New York, an ancient war rages unseen. The Black Dagger Brotherhood—an elite group of vampire warriors—stand as the last line of defense against the Lessening Society, a ruthless force determined to eradicate their kind. When Darius, a respected member of the Brotherhood, is killed, he leaves behind a final request: that Wrath, the reluctant king of the vampires, watch over his half-human daughter, Beth Randall. Unaware of her true heritage, Beth is suddenly thrust into a dangerous and hidden world she never knew existed. As Beth’s transformation approaches, her connection with Wrath intensifies, pulling them both into a powerful and forbidden bond. But as enemies close in and long-buried secrets surface, trust is tested and loyalties are pushed to their limits. In a world ruled by darkness, destiny, and blood, love may be the only thing strong enough to save them—or destroy everything.
