Imagine you were asked the same question again and again throughout your life. Imagine if it was a question that didn't bring about the happiest of memories. This is the experience of one-legged Joe, a child who just wants to have fun in the playground. Constantly seen first for his disability, Joe is fed up of only ever being asked about his leg. All he wants to do is play Pirates. But as usual, one after the other, all the children ask him the same...

The wizard Astrid is planning to cast the False Life spell which will bring to life the bones of giant ancient beasts and allow her to conquer all the kingdoms; in order to prevent her the Dragon Masters must find the Wind Dragon, the final dragon needed to undo the spell -- but that dragon and her Dragon Master are captives, and it is up to Drake and his friends to rescue them, and hope they are in time to stop Astrid.

A nest of baby Invisible Dragons has been discovered in Queen Sofia's castle, so Drake, Worm, and Val, Carlos's cousin, must journey to the dangerous Dove Island to find the parents and the fruit that keeps the dragons' invisible powers.
