A serious fantasy series that doesn't take itself seriously.

Fred and friends find themselves in a mess of new troubles as they continue their journey to destroy the Region Stones. The road takes them to the windy city of String where Fred is recruited by Ned to win the stone in a competition of flight. Troubles dog their steps as they face rival aviators, greedy merchants, and pointy hats. Will Fred survive the tournament, or will he go crashing down with everything else?
