Julian, heir to a prominent New York dynasty, inherits his family’s estate—only to uncover a century-old blood-sacrifice conspiracy orchestrated by Selene, the Werewolf Queen. Ryan, a werewolf, is coerced into infiltrating Julian’s inner circle to secure his blood, with Julian’s sister, Cora, held hostage. As Julian delves deeper, he unearths an ancient, long-forgotten pact and discovers that he carries the unique bloodline of the progenitors. During a climactic showdown at a full-moon auction, Julian springs a trap to dismantle Selene’s forces. He uses his own blood to save a dying Ryan, destroys the oppressive, archaic blood pact that had long exploited both species, and establishes a new agreement—one based on equality and peaceful coexistence between humans and werewolves.
