It's been a while, but I assume you're referring to the similarities drawn between information theory and sex. This was pretty offputting to me, until I realized the connection was deeper than I recognized - DNA is an apt comparison. I've read plenty of "pop math" books, and this one stands out as somewhat odd. It's also a quick read and, somewhat uncommonly, written by a person closely connected to the topic - so I'd recommend it.
