Sex at Dawn: The Prehistoric Origins of Modern Sexuality by Cacilda Jetha, Christopher Ryan

I broadly agree with the author's main thesis: that scientific research doesn't support the idea of biologically determined monogamy in humans. 

Aside from that, which could have been presented in an essay 1/10th the size of this book, I thought the book was quite weak. For as many sources as are cited, the author just as often relies on colloquial knowledge and loosely connected evolutionary psychology arguments. Many parts of the book arrive back to the gendered stereotypes about sexuality they aim to critique.
