In a world divided by blood and bound by prophecy, love may be the only force strong enough to end an ancient war. For centuries, the vampire kingdom of Nocthera and the werewolf realm of Theralis have been locked in a fragile truce--one held together by fear, deceit, and the memory of ruin. Princess Seraphina Valeheart, heir to the Vampire Throne, was born into duty and shadow, her power tempered by loss and the heavy crown of expectation. When visions of a dying moon begin haunting her, she is thrust into a web of secrets that threatens to tear her court apart. Far beyond the crimson spires of her home, Kael, a lowborn werewolf with no past and no pack, struggles to survive the aftermath of his family's destruction. But when fate draws him toward the heart of Nocthera, he discovers that the truth of his blood could shatter kingdoms--because he is the missing prince of Theralis, thought long dead. When Seraphina and Kael's paths cross at a moonlit masquerade, an impossible bond ignites between them--one that defies law, lineage, and destiny itself. Yet as forbidden love grows in the shadows, a darker power rises from the ashes of the old war: The Severed Throne, a force determined to plunge both realms into eternal night. Together, Seraphina and Kael must face treachery, prophecy, and the ghosts of their bloodlines to heal the wounds of a divided world...or watch it burn beneath the Blood and Moonlight.
