After years of comparative peace, darkness has fallen upon Ulster. Trouble is brewing and even those in the heart of the forest are not safe. Niamh, elder daughter of Sorcha, is required to make a strategic marriage, while her sister Liadan, who has the gift of Sight and her mother’s talent for healing, finds herself drawn into the shadowy world of the Painted Man and his warrior band. There Liadan begins a journey that is to transform her life.
