Eleven-year-old twins, Fox and Fibber, have been rivals for as long as they can remember.
Only one of them will inherit the family fortune and so a race is afoot to save the dwindling Petty-Squabble empire and win the love of their parents. But when the twins are whisked off to Jungledrop, a magical Unmapped Kingdom in charge of conjuring our world’s weather, things get wildly out of hand. An evil harpy called Morg is on the loose.
And if she finds the long-lost Forever Fern before the twins, both Jungledrop and our world will crumble. Suddenly, Fox and Fibber find themselves on an incredible adventure in a glow-in-the-dark rainforest full of golden panthers, gobblequick trees and enchanted temples. But, with the fate of two worlds in their hands, will the twins be able to work together for once to defeat Morg and her dark magic?
