Haiyi survives years of domestic cruelty under an abusive partner who drugs and strands her inside a desolate fortress on a full moon night. Instead of rogue scavengers, the crumbling halls shelter King Gareth, the feared sovereign of all packs, who loses control to lethal wolfsbane poison each lunar cycle.
Bound by an unexpected mate bond, Gareth executes retribution on her former tormentor and installs Haiyi within his palace under a protective covenant. As jealous noble consorts orchestrate deadly plots against her, Haiyi risks her life each month to soothe Gareth's monstrous fury, transforming a desperate survival pact into fierce devotion.
