"Between XX and XY" is a nice introduction to intersexuality and the variability when it comes to the human sexes.

I was especially interested to read about the differences between the various karyotypes.

What I didn't really like was how sensationalist the book was in certain sections. Those parts felt rather out of place.

This is a book best enjoyed by people who are not well-versed on the topic. However, I would caution these readers about the sensationalistic aspect of some parts of the book. I read it a while ago and have not made up my mind about whether or not I like it.

Fascinating exploration of gender, its role in society, and the people affected by variations on gender. Highly interesting and recommended.
