I picked this up because I very enjoyed Roach's book on the digestive system (Gulp) and it's only convinced me to pick up her other two books also. As with Gulp, she reviews vast amounts of scientific research on her current topic and then summarizes it in a very readable and often humorous form.

Bonk is about sex; it's not a sexy book, but it's a book about all the existing scientific research and knowledge about sex that the author could find, in great detail. I can't imagine there is anyone could read this book without learning something new. Fascinating reading (or listening). Can't wait to start her book on cadavers next.
