Emma Jean Lazarus is a lovable oddball who thinks she can use logic to solve the "messy" everyday problems of her seventh grade peers. It's easy--she just follows the example of her late father, a brilliant mathematician. Of course, the more Emma Jean gets involved, the messier her own life gets. Suddenly she's no longer the person standing on the outside of all social interactions. And that seems like a good thing, until Emma Jean's involvement lands her at the bottom of a tree, wondering why she ever got involved in the first place.
