Megan is excited when Cindy moves into her neighborhood -- maybe she'll finally have a best friend. Sure enough, the two girls quickly become inseparable. Cindy even starts to learn sign language so they can communicate more easily.

But when they go away to summer camp together, problems arise. Cindy feels left out, because Megan is spending all of her time with Lizzie, another deaf girl; Megan resents that Cindy is always trying to help her, even when she doesn't need help. Before they can mend their differences, both girls have to learn what it means to be a friend.
