Harley Hitch returns for an airborne adventure in this highly illustrated fiction series about a determined young inventor from award-winning author Vashti Hardy.

The Aviation Parade is coming to Forgetown this summer, and Harley has her sights set on creating a flying machine that will really stand out: a robot hippogriff! And if the creature impresses Cosmo’s mum enough, surely Cosmo will be able to keep it as a pet?

But Harley wants the flying machine to be a surprise for everyone. She soon finds that keeping secrets leads to tricky explanations and lots of trouble – especially when REAL hippogriffs arrive and cause chaos!
