Samuel is the only ordinary human boy in a world full of magic. Adopted by goblins, he dreams of being just like them: with their wicked sense of humour, love of farts and fighting, and amazing inventions. He is determined to get into the Goblin Academy and prove just how goblin he is. But things don’t go according to plan. Instead, Samuel finds himself recruited by a band of pirates on a mission to save the Goblin Empire from a dangerous spy.
