Keeping a Christmas Secret — Phyllis Reynolds Naylor

"Don't tell, don't tell," everyone keeps saying to Michael. And boy is it annoying. Of course he's not going to tell his dad what they got him for Christmas! Michael can keep a secret.When Michael does tell his father (though he's sure he was tricked into doing it), Christmas is almost ruined. But Michael comes up with his own special secret. And not only is Christmas saved, but Michael proves he can keep a secret after all!
