McCloskey changes from transvestite to transexual, and describes the heart-ache and practicalities that go with that.
It's an interesting story, but Deirdre has the immensely irritating habit of using the third person throughout. It's clearly a subjective and highly biased account, and the use of the third person feels terribly wrong. For me, that cost one star on its own. The unrestrained bias cost another.
Underneath that skin, though, this is a genuinely interesting story, and if you're interested in such things, it's worth a read.
