Boobela is a giant – a young, shy and rather lonely giant. Worm is a worm – wise and opinonated, but above all, he’s a clever and loyal friend. They live in a world that’s a lot like ours, but not quite. When Boobela meets Worm, she has the chance to overcome her fears, pursue her strange and magical powers … and have lots of funny, exciting and heart-stopping adventures with the kids at the balloon club, on her gran’s magic island and at the beach.
