The Crystal Cave (Arthurian Saga, #1)

Fifth century Britain is a country of chaos and division after the Roman withdrawal. This is the world of young Merlin, the illegitimate child of a South Wales princess who will not reveal to her son his father's true identity. Yet Merlin is an extraordinary child, aware at the earliest age that he possesses a great natural gift - the Sight. Against a background of invasion and imprisonment, wars and conquest, Merlin emerges into manhood, and accepts his dramatic role in the New Beginning - the coming of King Arthur.
