One bitter Midwinter's Eve, everything changes when Bridei finds a child on their doorstep - a child abandoned by the Fair Folk.
It is the height of ill fortune to have truck with the Fair Folk, and all in the area counsel the babe's death. But Bridei sees an old and precious magic at work and, heedless of the danger, fights to save the child. Broichan is wary but relents, for Bridei must grow to be his own man and make his own decisions.
As Bridei comes to manhood, he watches the shy girl Tuala blossom into a beautiful woman, and feels things he didn't know were possible.
Broichan sees the same process and feels only danger, for Tuala could be a key part in Bridei's future...or could spell his doom.
