The Sword and the Dragon is the first book in the Wardstone Trilogy. Two brothers with a magic ring and a special hawk are key players. A king's squire is another. They eventually unite to battle dragons, demons, and evil wizards. There are lots of interesting characters, plenty of battles, and a few beautiful maidens in this story.
Be aware this is the first part of a trilogy, but this tale comes to a satisfying, if bloody, conclusion. I wouldn't recommend this for younger readers because the level of violence is amazing. On the other hand, given the video games kids play these days this is probably kindergarten stuff. Highly recommended.
