His Billion-Dollar Lamb

22-year-old Ava Hart drowns in heavy debt after her mother’s death. She takes a mysterious high-paying interview invitation from Black Rose Manor, only to discover it’s a trap—she’s sold as a rare blood source at a vampire underground auction. The ancient Night King Lucien Blackwood bids 100 million to save her. Bound by a blood contract, Ava soon uncovers she is the long-lost sacred blood heir prophesied to crown Lucien, and they are each other’s destined fated partner.
