When Rachel's illegitimate baby brother is kidnapped by a travelling band of revivalists in 1940, she sets out with her grandfather, a hired hand, and an eccentric neighbor in a desperate attempt to steal him back.

Imprisoned by her wicked and power-hungry mother, Lady Rhiannon, Gwenore escapes to a women's healing community, later changing her name and becoming nursemaid and protector to the children of the magical king of Lir, who is now married to Rhiannon.
