Diary of a Would-Be Princess by Jessica Green (author) and Scholastic (illustrator) (UK edition)

Jillian wants to be as popular as the starry-eyed girls who rule her class. She’s even got an action-plan to transform herself into a proper princess. But when a bunch of dorky boys get in on the action, Jill learns that the higher you climb, the harder you fall. Is she about to crash-land? Exploring themes of friendship and individuality, this light-hearted comedy of errors will delight girls who love to be pretty in pink.
