If your blood doesn't boil reading this, then you're part of the problem, it should be mandatory reading for all males. It's page after page of unremitting evidence of the gender data gap, and how it effects every part of a woman's life; some of it simply beggars belief. I was expecting a dry and difficult to engage with wall of text, but it was very accessible and very well written; if you're into evidence, then the last third of the book is links to all the sources of the statistics and what not.
