Based on the Irish legends of Finn McCool, the Witches of Slivenamon were cursed to live the rest of their lives on Slievenamon, the mountain in Tipperary for imposing their own curse on the Irish hero.

In a contemporary romance widower Richard, an American, working in Ireland, and his daughter Caoimhe, meet Etain, one of the Witches of Slievenamon, who moves into the cottage next door to them and changes their lives forever.
