Beatrice Zinker, Upside Down Thinker: Incognito

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.
