In the kingdom of Aethelgard, home of the vampires, a crisis broke out. Their supply of animal blood was running low, and there was no easy solution in sight. The queen of Aethelgard and the mother of Primo Vein Ravenscroft, issued a strict law that no vampire is allowed to drink human blood. But her own brother, Vadenote, chose to defy her. He slipped into the human world and began feeding on people instead. Because of this, the Queen ordered her son, Primo, to go after his uncle and stop him. Primo didn’t understand it. Why was his mother being kind to humans, when humans were the ones who killed his father? Once he arrived in the human world, he met Hianna Cy Orell. She was his complete opposite. Where he was dark and cold, she was bright and full of dreams—even if she was a little slow. As days passed, they grew close. Neither of them expected that their bond would change both of their lives forever. And before they realized it, they had fallen for each other. A love that would end up putting both of them in danger.
