It is a very biased book. Maybe it is biased towards the right answer, I don't know, it is quite possible, but the thing is: it is written in a "biased way". The author does not try to tell you the story, she doesn't invite you to think together; she does not compare different claims, looking for their strong and weak sides. She is not engaged in a process of looking for an answer, and she doesn't engage you. She knows the answer, and everybody who don't adhere to her views are wrong. And it is annoying.

I hoped to read this short book to become more versed in the problem, but it is exactly the sort of book that can put somebody off from even trying to read about this subject. It turns this potentially very interesting and important subject in a barren and angry minefield, with author as a sniper on a tree, ready to shoot you immediately the moment you even think that there could be some differences between boys and girls. "The nature is more complex than it seems" she writes repeatedly, but then essentially simplifies it to one possible answer.

Also, as another reviewer mentioned, the intended audience is unclear. It is too boring for a layperson, as it has too many unexplained technicalities in it, but it is also boring for a specialist, as it rarely goes into details of the claims. It sits there in this no-mans-land (to be honest, most popular scientific books do), but it's really a shame considering, again, how potentially interesting and important, and universally loaded this question is.

I'll have to stay waiting for another book about sex and brain. ( )

This was really interesting I especially found the chapters, Gay Genes and Hormones, Sex and Gender very informative. The author writes in an easy to understand way, presents a lot of facts and shows the flaws of previous research. ( )
