Eleven-year-old twins, Fox and Fibber, have been rivals for as long as they remember – competing to save the Petty-Squabble empire, inherit the family fortune 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. If she finds the long-lost Forever Fern before the twins, both Jungledrop and our world will crumble.
With the fate of two worlds in their hands, will Fox and Fibber be able to work together for once to defeat Morg and her dark magic?
