When I have time to kill in a new library or bookstore, I inevitably find myself wandering to the math section — looking not for new textbooks but for decent books aimed at the popularization of mathematics. Sadly, the books I find are usually in one of three categories:

Drill books with hundreds of problems for young students to practice certain skills and procedures.

Cartoonish books aimed at a young elementary audience.

Fact books featuring short paragraphs on various topics in advanced mathematics.

There’s nothing particularly wrong with any of these types of books — and there’s a few that I could recommend from each category — but it’s rare to find a good math book that doesn’t fit one of these molds.

What’s unique about Math Girls is that the logical development of all of these topics are present, as opposed a cursory summary typically found in a book of mathematical facts. That said, the logical development is not the clean and sanitized presentation that would be found in a textbook. Instead, the topics are presented as if the young characters were discovering them for themselves, with more than a few false starts and mistakes along the way. In other words, the book feels a bit like the work of real mathematicians, which makes it fairly unique for math books intended for a popular audience.

Again, I’ll defer to MAA Reviews. and the Notices of the AMS for anyone interested in a lengthier review of the book. There’s also a second volume (Math Girls 2: Fermat’s Last Theorem) that I haven’t read yet, but I presume that the style is very similar.
