** spoiler alert ** 
 I remember thinking this book was AWESOME! I think it's because all the stuff from the past 4 books come together in this one, and there's a big battle, and all the bad guys and meanies reemerge, not to mention all the good guys. The 3 kids from books 1 and 3, Uncle whosis, the-boy-whose-name-I-hope-is-Will and some other members of his family, King Arthur's really blond son... they're all in it. There's a big fight. It's epic. Wow... I'm really going out on a limb here giving five stars to a book I don't remember a thing about other than I really liked it. The man on the white horse, though he's a bad guy, is awesome. I remember that much. So, if you're a young adult (which I always found to be a weird description of an age group that is just about to - or just hitting - puberty, but that's what they call them in the literary world), and like suspense, and a bit of mystery, and action, and adventure, and fantasy, then this is the book/series for you.
