The Hudson Valley in New York. Seraphina “Sera” Vale, 25 years old, is the daughter of the established vampire family Vale in North America – a daughter whose existence the family is reluctant to acknowledge. Her father is a Count among the vampires, while her mother is just a human woman. Serafiina possesses the rare Healing Bloodline, but due to her half-vampire status, she has been oppressed by her stepmother Evelyn and her older sister Isabella since she was young. The only person she has always trusted is her fiancé, Damian Blackwood. That is, until a charity event, when she saw with her own eyes that Damian kissed Isabella. What’s more, Damian didn’t even think he might lose her. In his world, Isabella could represent passion, while Serafiina would forever remain the woman who awaited marriage to him. On the same day, the Vale family received a notification from the Blood Court: they had to fulfill a covenant made three hundred years earlier. It was originally intended that Isabella, the legitimate daughter, should marry someone from Dragon Hollow.
