The subtitle of this book is: "One woman's journey into manhood and back again." Hmmm.
I went to a women's college, and so I've been in my fair share of fascinating, yet endless, discussions on the importance of gender and how much it is dictated by society or by biology.
The experience of dressing as a man for over a year must have been incredibly eye-opening and scary, but the majority of the book reads as plainly (and uninterestingly) as a food diary. For someone who really wants to delve into the differences between men and women's behavior and perceptions of each other, I'd recommend that you skip over the majority of the book and just read the chapter entitled "Dating."
