In the kingdom of Galaxandria, Princess Celeste Starwing is in BIG trouble. After one bratty incident too many, her father decides she needs to learn a lesson - and so she's packed off to the Intergalactic Post Office, and given a mission to whip it into shape. Otherwise it's goodbye to being a princess forever - gulp!

But Celeste and her new assistant, Podge, soon find they're up against a more than just towering piles of unsent letters. Mysterious portal magic known as wurms are putting them out of business - and it looks like the wurms are more sinister than anyone could know. In fact, they might have something to do with Celeste's mother, who she's never known . . .

Now it's up to Celeste and Podge - and their adorable collection of Stardust Bunnies - to stop the wurms, uncover what happened to Celeste's mother - and maybe save the galaxy while they're at it.

This out-of-this world story is stuffed full of incredible adventure, brilliant intergalactic worlds, and amazing cartoon-style artwork - perfect for fans of Super Mario Bros, Amelia Fang, Peanut Jones and Adventures on Trains.
