This is exactly the kind of middle-grade novel that deserves its buzz. Lucy is a math genius, yes, but McAnulty makes her wonderfully three-dimensional—anxious, stubborn, funny, and real. The book doesn't try to 'fix' her neurodivergent traits; instead, it shows her learning to expand her world while staying true to herself.

The four-challenge framework (make a friend, join an activity, read a non-math book, survive middle school) gives the story momentum without feeling contrived. It's the kind of book that sneaks in big themes—neurodiversity, stepping outside comfort zones, the value of human connection—without ever feeling like a lesson.

At 4.8 stars on Amazon and recognition from NPR and Kirkus, this has both parent approval and actual kid appeal. It's genuinely funny, moves quickly, and respects its readers. If your kid loved 'Counting by Sevens' or 'Wonder,' this belongs on the same shelf. And if your kid IS the rigid-routine, special-interest, socially-anxious type? Even better—they'll see themselves portrayed with dignity and humor.
