I was talking to a coworker the other day about people who undergo sex change operations. It's something she was having trouble understanding, so I told her to read She's Not There: A Life in Two Genders by Jennifer Finney Boylan. A creative writing professor at a liberal arts college in Maine, married with two kids, James Finney Boylan decides he was meant to live life as a woman. The book is about his life leading up to that point and explains a lot of the actual process of going about changing genders. A really interesting and well-written book -- I loved the parts about Finney Boylan going out with his drinking buddy Richard Russo.
