Finally, a book about man that's not just what some woman thinks! The idea that this woman got a professional surveyer to come in and survey men, in addition to her one-on-one interviews to try and understand them is amazing. Extremely well-written, dealing with some rather difficult issues for us women to face at times, but great insight into how the male mind works.
