There's nothing unusual about the Brockets. Normal, respectable, and proud of it, they turn up their noses at anyone strange or different. But from the moment Barnaby Brocket comes into the world, it's clear he's anything but ordinary. To his parents' horror, Barnaby defies the laws of gravity - and floats.
Desperate to please his parents, Barnaby does his best to keep both feet on the ground - but he just can't do it. One fateful day, the Brockets decide enough is enough. They never asked for a weird, abnormal,floatingchild. Barnaby has to go . . .
Betrayed, frightened and alone, Barnaby floats into the path of a very special hot air balloon - and so begins a magical journey around the world, with a cast of extraordinary new friends.
