‘A wonderful, riveting story’ Barbara ErskineA magnificent saga set in the Celtic twilight of 10th century Ireland, when myth was law and magic was a power of nature, brilliantly brought to life: the legendary story of an evil stepmother opposed by a seventh child.The keep at Sevenwaters is a strange, remote place, guarded by silent men who slip through the woodlands clothed in grey, and keep their weapons sharp. Invaders roam outside: raiders from across the sea bent on destruction. But now there is also an invader inside the keep: the Lady Oonagh, a sorceress as fair as day, with a heart as black as night.Oonagh captivates Lord Colum and his six sons, but she cannot enchant his daughter, Sorcha. Frustrated in her attempts to destroy the family, Oonagh binds the brothers with a spell only Sorcha can lift. If she fails, they will die.When the raiders break through, Sorcha is taken captive. Soon she will find herself torn between her duty to break the curse and a growing, forbidden love for her captor.
