You Can't Eat a Princess! — Gillian Rogerson

It's Princess Spaghetti's birthday, but her father King Cupcake has been kidnapped by aliens! Without a moment to spare, Princess cranks up the royal rocket ship and zooms into space on a rescue mission. In record time, she discovers the offending group of aliens just as they are about to turn her father into a vat of soup. But how can one tiny little princess overtake an entire group of aliens? And what on earth could chocolate have to do with any of it?
