My favorite book of the series and the first of what is, in many peoples' opinions, the definitive Arthurian cycle.
This book starts with Merlin as a child. Since I've always found Merlin far more interesting than Arthur, this immediately sucked me in. Stewart always writes wonderful books and her long history as a best selling novelist is evident in the finely crafted story with its wonderful details and settings and complex characters.
A fine first book to the best series ever written about Arthurian times.
