This book is a compilation of short biographies of some very impressive women. I really love reading inspirational stories of women who beat the odds and become very successful at what they love to do (and even more so if they succeed in predominantly male areas), so I should have loved this book. Yet, l'm a bit disappointed.
The tone of this book is very colloquial. That is not a bad thing per se, but the author tried to find "that sweet spot somewhere between textbook and Tumblr", which is not for me. It is a little bit too much on the Tumblr side, making it hard to take the stories seriously. What bugged me even more was, that the style is not just informative, but that the author gives her own opinion on everything (explicitly by writing things like "that's cool" and "this is so impressive, considering ..." and implicitly by choosing to almost only write positive things about these ladies). This makes it hard for the reader to form their own opinion (because yes, a person can do remarkable things and be very successful while having to fight the patriarchy, and still be unlikeable!).
Furthermore, the "man-hating" tone in most stories was a bit too much. Almost every man is "some dude" and the author chooses to highlight the bad men over the good ones (she does, for example, not even mention David Hilbert by name, although he is crucial to Emmy Noether's success and definitely one of the good guys). This is done, of course, to emphasize just how remarkable these women were, but I think that it is possible to marvel at their achievements without looking down on men.
All in all, this book seems to be overly motivated to "sell" these female accomplishments. This is not necessary, because the accomplishments are great enough on their own, they do not need this over-selling.
Another (although small) downside is, that there are some typos and incomplete sentences throughout this book.
On a positive note: I really like the look of the book, and the cute illustrations. I also like that it does include women scientists, doctors, spys, inventors and adventures (although the choice for one field seems quite random and is never really explained). The women mentioned in this book all really did very impressive things and most of their stories are very inspirational. I also liked the interviews with women who are working in the respective fields today, and would have liked more than one interview per field (although, again, the choice of interview partner seems quite random).
This book is best suited for young women who already are in a predominantly male profession or studying something in a "male" field, and who are going through a tough phase. In this (quite specific) circumstances, this book might have the power to motivate them and lift them up. They should hurry, though, because the Tumblr tone will be outdated quite soon ;).
