Trevor is a goblin - a goblin with serious problems. He farts, he burps, he is in a heap of trouble and he has just landed in the back garden of two teenagers. Sisters Hannah and Phoebe are plunged into a world of mythical mayhem, troublesome trolls, uncivilized unicorns, dangerous dragons, a wicked witch and a lot of farting after Hannah finds the mean, green, stinking machine in the bottom of her school bag. Arrogant Trevor needs Hannah and Phoebe to help him save his world from a tyrant and together the three of them embark on an adventure filled with laughter, fantasy and danger as they attempt to bring peace to his land. Trevor is a story filled with action, magic and a fair dose of sarcasm.
