Beatrice Zinker, Upside Down Thinker

Beatrice 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! Can Beatrice use her topsy-turvy way of thinking to save the mission, mend their friendship, and flip things sunny-side up?

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.
