A frontline warrior returns home to the Blood Moon pack expecting a joyous reunion with her closest childhood friend Selene, the reigning Luna. Instead, a chilling memory takes over: Selene's parting warning never to trust anyone claiming to be her if seen consuming lethal nuts. Sitting at the grand banquet table, the smiling woman possesses Selene's face, voice, and intimate memories—yet blithely chews the forbidden poison.
Realizing a cunning doppelgänger has seized the throne, the warrior feigns ignorance while hunting for clues about Selene's disappearance. The impostor tightens control over pack elders, orchestrating executions against anyone who looks too closely. In a compound governed by paranoia, the loyal soldier must uncover the captive Luna's secret cell before the pretender eliminates everyone who knows the truth.
