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.
