There is an absolutely coruscating review of Conundrum by Nora Ephron. I can't find it online but I do commend it to you.
Here's a blog including a quote from it (and several others): zagria.blogspot.com/2013/11/jan-morris-1926-part-3-travel-writer.html#.Y5T5x33P02w
And, if you CBA to click on it, here's the Ephron quote (which reminds me somehow of Dylan Mulvaney....):
"I always wanted to be a girl, too. I, too, felt that I was born into the wrong body, a body that refused, in spite of every imprecation and exercise I could manage, to become anything but the boyish, lean thing it was... I wanted more than anything to be something I will never be – Feminine and feminine in the worst way. Submissive. Dependent. Soft-spoken. Coquettish. I was no good at all at any of it, no good at being a girl; on the other hand I am not half bad at being a woman. In contrast Jan Morris is perfectly awful at being a woman; what she has become instead is precisely what James Morris wanted to become all those years ago. A girl. And worse, a forty-seven-year-old girl. And worst of all, a forty-seven-year-old Cosmopolitan girl."
