Their marriage is his revenge!
For Isolda de Lara, the day she will be a bride will also be the day she will bury her soul. To end a war that has been going on for years, but also to protect her subjects in the kingdom, the princess must marry the vampire king Adrian Aleksandr Vasiliev and kill him.
However, her assassination attempt is thwarted, and Adrian warns his beautiful fiancée, Isolda, that if she tries to kill him again, he will turn her into an undead. Afraid that she might become the thing she hates most in the world, the young woman looks for other ways to defy the sovereign and survive the outpouring of violence, but also the political machinations of the terrible royal court of vampires.
Except that the princess is not afraid of them the most, but of Adrian himself and the uncontrollable attraction he exerts on her. Shrouded in mystery and a prisoner of a past he refuses to talk about, the vampire king begins to seem less and less of a monster to Isolde. Despite the undeniable passion that binds them, Isolde wonders why the sovereign - fierce, cruel, merciless, but sometimes inexplicably tender - chose her as his wife.
The answer he gets will shatter his world.
