DRAGON RIDER was actually Cornelia Funke's first book in Germany, but it wasn't offered in English until after the success of her two other books. Despite its excessive length, it's aimed at a younger audience with a simple, straightforward plot, one-dimensional characters, and a gentle approach that, while exciting, eschews violence. The villain is all bark and bad temper, most of the characters are helpful and kind, and the ending is predictable, but satisfying.
It reads like a middle-grade novel -- well, all right, three middle-grade novels. Ambitious young readers will want to read this themselves, but it would be a great extended bedtime read-aloud -- exciting but not too scary, humorous, with short chapters, and plenty of cliffhangers.
