Seren has spent her life as an Unclaimed in Moonhaven, raised by the mysterious Old Maren and working at The Howling Hearth. She has no known parents, no pack, and no explanation for the strange humming beneath her skin. Everything changes when Kael, a powerful stranger hiding his identity, enters the tavern. Seren soon discovers he is the future Alpha King, chosen by the Moon Goddess Lunara to unite the Five Kingdoms. Their unexpected connection becomes impossible to ignore, and one night together awakens something neither of them understands. But Seren’s life is tied to secrets far older than either of them. As her hidden identity begins to surface, Seren discovers a connection to the Ashwood throne, an unknown twin named Cassius, and a prophecy involving the Twin Moons. Her awakening draws the attention of enemies who have waited centuries for the right moment to strike. Meanwhile, Kael carries a dangerous secret of his own: the Hollow’s mysterious mark is spreading, linking him to an ancient force threatening the kingdoms. The Oracle Council is corrupted, Archon Vell serves the Hollow, and Queen Mother Isolde hides a connection to Protocol Silver. Then the long-forgotten Silver Curse returns. As the Blood Moon approaches, political alliances collapse, kingdoms turn against one another, and Seren must learn the truth about her bloodline and the power awakening inside her. Kael must choose between the crown he was born to carry and the woman who may be the key to saving—or destroying—the werewolf world. With betrayal, forbidden secrets, ancient magic, and the final Eclipse approaching, Seren and Kael will discover that their meeting was never an accident. Their bond may decide the fate of every kingdom.
