Nova, a mixed-blood vampire ostracized by her clan, is forced to fulfill her betrothal to Kane, the young lord of the Caster family, solely to protect her mother’s legacy.
Meanwhile, Kane is desperately searching for the mysterious woman who saved his life and shared a passionate one-night stand with him. Unbeknownst to him, his mother, Della, driven by a twisted obsession with Nova’s late mother, Celine, uses forbidden blood magic to manipulate Nova. Della's goal is to force the two into an engagement for her own ends, only to tear them apart once her plotting succeeds.
Supported by Kane—who risks his life to protect her—Nova plays a dangerous game. She feigns absolute submission to Della while secretly gathering evidence and searching for a way to break the magical thrall.
Ultimately, Nova and Kane join forces to expose Della’s schemes, vindicate Celine's memory, and cement their place as each other's sole eternal bond.
