Lots of cool examples, but you can tell he doesn't critically evaluate his sources much in the book. It was a series of annecdotes more than a coherent look at the comprehensive history of women rulers or women warriors. For example, he didn't really talk about why there have been so few women warlords, or why they're not well known (hint: sexism, not a recent development). It would also have been neat to read about what factors seem to promote women warlords (some cultures more friendly to the idea than others? Desperation? Sheer individual talent?). It was very focused on the western world, with very few examples that weren't European. Good read, very interesting, good writing style, but not meant as scholarly history.
