Whilst staying at her grandma's during the school holidays, Isla discovers a mystical-looking book which transports her off to the magical land of Atalan. On her arrival, she meets the Unkerdunkies, a tribe of elf-like people who live in the forest. Two of the Unkerdunkies, Fartybubble and Oliver, befriend Isla and help her in her quest to find a way home. What follows is an exciting adventure through Atalan as the trio find themselves chased by dragon-like creatures, encounter giant trolls and battle vicious goblins.
