Searching for his father, who vanished 25 years ago, Elias Hart breaks into an underground casino—and discovers a world ruled by vampires. When a hitman targets him, the ruthless Vampire King, Lucian Vale, claims Elias as his own and places him under House Vale’s protection. But Elias refuses to be anyone’s pet. As he investigates his father’s disappearance and a stolen Blood Signet, deadly attacks expose a conspiracy among the ancient vampire houses. Then Lucian’s immortal former lover, Cassian, returns, bringing a century-old bond back to life. Elias soon uncovers a devastating secret: Lucian once signed his father’s execution order. With trust shattered, Lucian must learn that love means letting Elias walk away. But when Elias faces death, he must make the ultimate choice: become immortal and risk losing himself, or walk away from the vampire king forever. In the end, only one thing can prove their love—Elias choosing to stay when he is finally free.
