Twenty-three years after her supernatural bloodline was declared extinct, a young woman discovers she is the last surviving Aether Wolf when the feared Alpha King recognizes her as his fated mate, forcing them both into a dangerous struggle against the political dynasty responsible for destroying her family.

Cassian is the Alpha of the most ruthless pack in history, a man who commands fear and expects absolute loyalty. Zaria is a servant in his palace, a girl with no name and a past buried in ash. She is not what she seems, and Cassian senses it. He suspects she is the last of the Eclipse Blood, the ancient lineage his own ancestors hunted to extinction. He keeps her close, not as a mate, but as a prisoner, haunted by the fear of the day her true power awakens. But the bond between them is a wildfire he cannot control. As Zaria’s memories return and the truth of his family's crimes comes to light, the Alpha must make a choice. Will he be the executioner his bloodline demands, or will he burn his own legacy to save the woman who was meant to destroy him?
