It looks like a lonely summer ahead for Tracy Matson. She's the only girl her age in the small town of High Flats. And Leroy Wilson, the only boy, thinks she's a know-it-all, even after Tracy tries to make friends by giving him a chocolate-icing-on-rye sandwich.

What if Casey—who wants to be a writer—finds out that Tracy is really a rotten reader? Suppose Leroy spills the beans?
