Max really wants a pet. His parents aren't so sure. Puppies chew, parrots screech and sharks have too many teeth. How about a dragon? Max's parents say that dragons don't exist, so Max settles for a pet worm instead. Except this particular worm turns out to be very unusual when its back begins to turn spiky and it starts to breathe smoke ... Dragons don't exist. Do they? A funny and light-hearted story from much-loved children's author Debi Gliori, perfect for any child who has ever wanted a pet. With an added cautionary tale about being careful what you wish for.
