125. Roach, Mary. Bonk: The Curious Coupling of Science and Sex. 303 pages. 10.29.09.

Mary Roach, author of Stiff and Spook, hits the monosyllables once again with her latest publication, Bonk, which journeys through the world of science to see exactly what the field is doing with de Sade's favorite subject. Bonk is a thoroughly enjoyable romp through physiological research; Roach focuses on the scientific over the pornographic, making her work comfortable for wide audiences. Her voice is frank, and she jumps into her research feet-first, even to the point of participating in some of the studies she observes. Through it all her sense of humor shines through, and the entertainment value is high.
