Sorcha Campbell never expected to lead her clan, but when a deadly illness strikes and her brother falls ill, she is thrust into the role of lady of the Campbell clan. Desperate to save her people and her ailing sister, Sorcha refuses to believe they are cursed and fights to find a cure.

Malcolm, a formidable warrior immune to the disease, becomes her unlikely ally. He agrees to help Sorcha seek out Laird Fraser—a man born of royal blood, a fierce warrior, and known as the "wolf-bane" for slaying a wolf as a boy—the only one who might lift the curse before the next full moon in 17 days.

As they journey through the treacherous Highlands, they uncover hidden enemies and unexpected allies. An undeniable bond grows between Sorcha and Malcolm, but they both know they can never be together. With time running out and danger closing in, Sorcha must choose between her duty and her heart.

Will they find the elusive Wolf Killer in time to save her clan, or will Sorcha discover that the true hero has been by her side all along?
