Arthur has probably before been called an instant classic, and I think it earned that. From the beginning of Arthur's reign (before, actually) to the book's surprise ending, Arthur is a realistic version of many and diverse Arthurian myths, legends, and perhaps true stories. Arthur is the climax of the Pendragon Cycle. Those first two books, Taliesin and Merlin, they were just setting this one up. This book was quite excellent. The three parts were written by three different characters, giving three different viewpoints of the High King and Pendragon Arthur. From epic battle to epic battle, the book holds the fantastic yet realistic quality seen in the first two Pendragon Cycle books. Still, I have to admit that the ending did, to be discreet, surprise me. I'm not sure what I was expecting, but this wasn't it. Can't say more, otherwise this won't get posted, and you won't see any. Despite the interesting ending, this book was a great climax to Taliesin and Merlin, and I look forward to reading Pendragon and Grail.
