Taren of Caer Dallben wanted to defeat Arawn and be wed to one of his friends Eilonwy. He couldn’t defeat Arawn alone so he asked some of his old friends to help him along the side of Lord Gwydion. He couldn’t marry Eilonwy because she is of royal blood and Taran doesn’t know whether he is or not. In the end, Taran defeats Arawn and marries Eilonwy.
I really liked this book. I liked how the story changed the point of view for each character from time to time. I thought that the climax was very thrilling. I thought that the end was a little sad, while at the same time happy.
