This is book number 3 in the Beatrice Zinker, Upside Down Thinker series.


The third caper is the zaniest yet for Beatrice Zinker, the irrepressible third grader who marches to the beat of her own drum--and does her best thinking upside down!
With several successful Operation Upside missions under their belts, Beatrice, her best friend Lenny, and Sam have made quite a name for themselves--they're the people who remind you there are infinite upsides to being yourself. But suddenly the unthinkable occurs--an imposter delivers an imitation Upside Award that could only be give by Beatrice, Lenny, or Sam!
As Beatrice hunts for clues to the culprit, Lenny suspects one of their own. Will they solve the mystery before Operation Upside becomes a fraud and is ruined once and for all? Or is the situation much bigger than any of them imagines?
This highly illustrated chapter book series that's perfect for emerging readers celebrates a creative, compassionate kid who's fully herself and inspires others to embrace their individuality, again and again.
