Jesobel Jones is bold and beautiful. The daughter of a hand model and a washed-up rock star, she sees no need to apologise for her rambling house, her imperfect family, her single status... or her weight. Jess makes her own cupcakes and she eats them, too. That is, until own clothes day rolls around. Jess and her friends dedicate the required hours of planning to their outfits.

But a wardrobe malfunction leaves Jess exposed, and a mean girl calling her the one thing that's never bothered her before: fat.
