I'm going to tell you the word that ruins my entire life: BIG. Because my name is Jemima Small. But I am exactly the opposite.

Jemima Small is funny and smart. She knows a lot of things. Like the fact that she's made of 206 bones, over 600 muscles and trillions of cells. What she doesn't know is how that can be true and yet she can still sometimes feel like nothing… Or how being made to join the school's "special" healthy lifestyle group - aka Fat Club - could feel any less special. But Jemima also knows that the biggest stars in the universe are the brightest. And maybe it's her time to shine…
