Incognito (Beatrice Zinker, Upside Down Thinker, Bk. 2)

Beatrice Zinker's top-secret plan, Operation Upside, is finally in full swing! And she's REALLY EXCITED ABOUT IT! But when Beatrice impulsively awards her teacher, Mrs. Tamarack, an UPSIDE of her own-with the words Most Strict lettered in gold-the team has to put the entire mission on hold to avoid suspicion.

Lying low isn't exactly Beatrice's strong suit . . . and her classmate Wes desperately needs to be recognized. When Wes's certificate falls into the wrong hands, Beatrice and her best friend, Lenny, must find a way once again, to save Operation Upside - and themselves - from big trouble.
