Beatrice Zinker, Upside Down Thinker

Meet Beatrice Zinker, who does her best thinking upside down! Hanging from trees by her knees, doing handstands...for Beatrice Zinker, upside down works every time. She was definitely upside down when she and her best friend, Lenny, agreed to wear matching ninja suits on the first day of third grade. But when Beatrice shows up at school dressed in black, Lenny arrives with a cool new outfit and a cool new friend. Even worse, she seems to have forgotten all about the top-secret operation they planned!

In book two of the delightfully energetic Beatrice Zinker series, Operation Upside is finally in full swing! But when Beatrice's overenthusiasm lands Mrs Tamarack with a Strictest Certificate, the team has to hold off on any new missions to avoid suspicion. Lying low is not exactly Beatrice's strong suit, especially when she sees someone who desperately needs to be recognised. But when the certificate meant for him falls into the wrong hands, Beatrice and Lenny must find a way to widen their circle once again to save Operation Upside, and themselves, from trouble.

Operation Upside has grown to a team of three: Beatrice, her best friend Lenny and her mysterious neighbour Sam. With several successful missions under their belts, the trio is preparing for another great week when the unthinkable occurs – an impostor delivers an imitation Upside Award! As Beatrice hunts for clues to the culprit, Lenny suspects one of their own. Will they solve the mystery before Operation Upside is ruined once and for all? Or is the situation much bigger than any of them imagines?
