Beatrice Zinker, Upside Down Thinker, Book 2 Incognito

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 recognized. 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.
