I have loved the Dream of Eagles series from the very beginning, so it was a with a great deal of disappointment that rather than use the rich, flawed characters of the Arthur legend, Jack Whyte made Arthur, Lancelet, Guinevere, and Mordred into flat, flawless, and perfect characters. These characters were so loyal and honourable that not a single element of the Arthur legend--the love triangle between Arthur, Guinevere, and Lancelot, Mordred's betrayal, and Elaine's relationship to Lancelot--were at all preserved or used. They led perfect lives, respectful of each other, and then the entire Arthurian legend was summarized in 100 pages at the end, basically saying that none of it was true. Lancelot, in fact, wasn't even present in Camulod for nearly the entire book, spanning more than a decade!
The other books in the Dream of Eagles series were so spectacular, that I question why it was based on the Arthurian legend at all, when the story of Arthur played so little part. There was no climax to this story. Maybe Mr. Whyte was sick of writing the story?
I wish that Jack Whyte had ended the Eagle, leaving the Arthurian legend for another book, sometime when he was up to the challenge. The rest of his novels in the series were truly great and the Eagle did not do them justice.
