*So you're in the woods in the middle of the night, and a huge purple monster tries to eat your flashlight. What do you do?
Meet Portia Bennett, who is almost certainly braver than you are - she brings the monster home and offers him a tuna sandwich. And just like that, Portia has a new (secret) best friend. Life with Jellaby is exciting, but Portia's purple friend has secrets of his own. Convinced that the sweet, silent monster is lost, Portia decides to help him find his home. But their only clue is a photograph of a mysterious door in a nearby city. How can a ten-year-old girl and a purple creature of unknown origin make their way into Toronto all by themselves? *Source: Back Cover
