Another day. Another mood. Meet Judy Moody at her moodiest-best, in this laugh-a-minute twelfth adventure in the international bestselling series.

On Backwards Day Judy Moody double-dares herself to become Queen of the Good Mood. Soon she's turning her frown upside down, making lemonade out of lemons and even being nice to her little brother. In fact, Judy becomes a NOT moody, cool-as-a-cucumber neat freak for one whole entire day. But when her combed hair, matching outfits and good moods hang around for days after, her friends begin to worry. Could this smiley Judy be an imposter?
