Dragon Castle book by Joseph Bruchac

Young Prince Rashko is frustrated with his family - no one does any thinking but him! The kingdom and castle seem to be in the hands of fools. So when Rashko's parents mysteriously disappear and the evil Baron Temny parks his army outside the castle walls, it is up to the young prince to save the day. But there is more to this castle and its history than meets the eye, and Rashko will have to embrace his ancestry, harness a dragon, and use his sword-fighting skills to stop the baron and save the kingdom. Along the way, he realizes that his family is not quite as stupid as he always thought.

Master storyteller Joseph Bruchac, known for his smart, gripping Native American books, here combines his signature action and adventure with a large dose of humor, which just brings this story to a whole new level.
