Damn I like this book.
It's got everything. Kings, castles, knights, rescuing a damsel in distress - who then turns around and rescues her rescuer! - camaraderie, some mystery and intrigue, humor, history, romance. Or, to quote another good read, it's got -- "fighting, fencing, giants, villains, escapes, true love" :)
Set in Palestine in the years following the First Crusade, the writing is so vivid you can, as another reviewer said, almost smell the camels. The descriptions put you right there. History is given as backstory, but it's unobtrusive, and even minor characters are fleshed out. I guess what makes this book really stand out for me is that it's as if it really happened.
That's not so usual as you'd think.
