Definitely has my interest. For $5.50, ordered it on Amazon. I look forward to reading it after I wrap up with my current list. ("Berdan's United States Sharpshooters in the Army of the Potomac" and "The Crusades: The Authoritative History of the War for the Holy Land")
Morgan Llywelyn does several excellent books on celtic history and myth, including the fall of Ghaul and 'end' of druidism, which is one of my favorite books ever.
Stephen Lawhead is a small god among historical fiction, from what I hear. He does the crusades, an arthur series I believe, and a very awesome Robin Hood retelling. He does so much research and explains the derivative of his tales so engagingly that I actually read his forwards.
Jack Whyte does an interesting series Authurian series that begins with the man who discovers the metal the sword is forged from. I overdosed on Authurian books so I never actually got to the part of the series where Authur is born, so I don't know where it goes from there, but the first two books were great!
