This is the second book in the Seven Waters trilogy, which tells the story of the last days of pre-Christian Ireland. "Son of Shadows" tells the story of the children of Sorcha (the heroine of the first book, who saved her enchanted brothers) and her husband, the British Hugh.

The beloved, obedient daughter of her parents, Liadan goes on an unexpected journey that makes her realize how the peace and tranquility to which she is so accustomed has been hard won. Liadan will need all her courage to save her family, whose peace and happiness - and at the same time her entire world - are about to be destroyed by ancient and dark forces. And she will also need all her strength to go against the will of her most beloved people, because the path Liadan chooses in search of true love will determine universal destruction... or salvation.

This is a smart historical novel, in which miracles are so naturally woven into the daily lives of the characters that it is impossible to think of this book as a work of fantasy - it is simply a story about people for whom witchcraft and conversations with forest spirits are natural and ordinary.
