A modern city hides wolfkin secrets split into Dayblood purebloods, rebel Night Wolves, and vulnerable half-bloods caught between them. Dayblood warrior Darius is tasked to infiltrate orphanage volunteer Clara, using her to hunt fugitive half-blood teen Ethan for his clan.
Night Wolf leader Kogan stirs serial child disappearances, framing Daybloods and manipulating Darius and Clara to fall in love. He aims to expose Darius’s wolf identity to ruin the pair and seize Ethan’s rare blood with the forbidden Moon-Devouring Mark to seize power.
Darius grows fond of Clara and repeatedly hides his wolf powers to protect her, arousing her suspicion. She researches countermeasures against wolfkin and uncovers his lies. On a full moon, Darius loses control and reveals his beast form; heartbroken Clara cuts ties. Kogan sends assassins after her, pushing Darius to defect. Fleeing together, they meet Ethan, who joins them to fight Kogan, scarred by his family’s murder.
