Merlin. Technically it's a TV show, but it is AWESOME. Very well-written, likeable characters (and characters you love to hate! he he), funny at times, romantic at times, and sitting-on-the-edge-of-your-seat at times! It starts out good, and the story gets better and better and better as you go along. It's family-oriented, and even though they have sword fights and run into all kinds of perils, they don't actually show anything gory. It's got something for everyone. I didn't expect to like it, but it turns out that I *love* it!
Here's a link to IMDB:

"Young Merlin is a teenager, discovering and then learning to master his magical gift. Magister Gaius, King Uther Pendragon's learned court physician to whom he's assigned as humble page, teaches him medicine, coaches his magical self-study, and warns him of Uther's strong aversion to magic. Merlin becomes squire to the noble but imprudent crown prince, Arthur, whose fate is linked with Merlin."
