I've gotta say that Mary Stewart's "Crystal Cave" is the reason I became a fantasy fan, which grew into a degree in medieval history. What I love about Jack Whyte is the believability. It totally fits with the historical reality of the time, and his writing makes me feel like I could have been part of it. What it shares with Mary Stewart is that I take a serious break from reality because I can't put it down! Great taste in books, who else do you suggest for any fantasy? My other favorite author is Raymond Feist.
