In need of an heir, Arran has finally agreed to take a wife, but when he sees Breghan's fragile beauty, he's furious. He will not risk the life of another maiden by getting her with child. Lust prompts him to offer a compromise: necessary precautions, and handfasting for a year and a day, after which Breghan will be free. For a chance to control her own future, Breghan makes a deal with the Devil.
Passion quickly turns to love, but Arran still has no intention of keeping the lass, or making her a mother. He loves her too much to lose her. But when a treasonous plot threatens queen and country, Breghan has to prove only she is woman enough to stand by his side.
