Iona Sheehan grew up craving devotion and acceptance. From her maternal grandmother, she learned where to find both: County Mayo, Ireland. Iona arrives in Ireland with nothing but her Nans directions, an unfailingly optimistic attitude, and an innate talent with horses. There she finds her cousins, Branna and Connor ODwyer., and they invite her into their lives. When Iona lands a job at the local stables, she meets the owner, Boyle McGrath. Iona realizes that here she live her life as she wants, even if that means falling for Boyle. But an ancient evil has wound its way around Ionas family tree and must be defeated.
