Cousins Good Knight (Godwin) and Bad Knight (Berk) are helping their friends Willow and Warrick and their families fix up their falling-down cottage. When Warrick botches a spell, he and his sister are banned from doing magic. Desperate for something to bring him fame and fortune, Warrick decides to build a flying machine.

The friends’ early test flights all end in disaster, so they travel to the mountains to study the best flyers of all - eagles. What they find there is a dragon with a dangerous grudge and very bad breath.

Will they make the machine, tame the vengeful dragon and get back to Godwin’s island in time to defeat marauding barbarians?

Hold onto your helmets for a new armour-rattling adventure from Tom Knight!
