December Secrets — Patricia Reilly Giff

December is a time for gift giving. This month everyone in Ms. Rooney's room has chosen a special person to be kind to. All the kids are happy with their secret friends except Emily Arrow. Because she was the last one to pick, Emily is stuck with fat Jill Simon. Jill is the class crybaby, and Emily makes up her mind she will make Jill happier -- and thinner. At the same time Emily's getting lots of super presents herself -- and she's almost sure they're from Dawn Tiffanie Bosco, who's been mean to her.

Just before Christmas the secrets are told, and Emily learns what being a special friend really means.
