On a full-moon night, human doctor Ethan Carter finds a fierce werewolf patient on a hospital rooftop—sneezing, tearing up, and strangely allergic to moonlight. His name is Caleb Wolfe, the pure-blood heir of the werewolf clan, but his failed transformations have made him a laughingstock.
As Ethan treats him, he discovers Caleb’s “moon allergy” is not a weakness at all, but the result of a moonsilver poison planted in him for sixteen years. To save Caleb, Ethan enters the dangerous world of werewolf politics, uncovers a conspiracy led by the Grand Elder, and becomes the one person who can calm Caleb’s wolf soul.
From doctor and patient to fake mates, from medical treatment to forbidden love, Ethan and Caleb fight poison, betrayal, and clan law together. In the final full-moon ritual, Caleb completes his true transformation, exposes the traitor, becomes the new chief, and finally learns that the moon was never his curse—it was the light that led him home.
