Amber Brown isn't entirely ready for fourth grade. She has her pens, pencils, new clothes, and new shoes. But the one thing she doesn't have is her best friend, Justin Daniels. Justin has moved away, leaving Amber utterly best friend-less. Amber knows Justin can't be replaced, but she is on the lookout for a new friend. Brandi seems a likely choice--but does Brandi want to choose Amber in return? Will Amber Brown go fourth, and go forth, with a new best friend?
