Second paragraph of third chapter:

Robinski looked charming in her simple rages. Her one perverted extravagance, was a pair of shoes with flat mirror buckles. She was knickerless and her pudenda shone brightly from her feet. Her footwear had been a gift from Fatman; and yet another example of his peculiar sexual tastes.

This book is a novel by ’70s sex symbol Fiona Richmond, about a young woman astronaut whose husband, also an astronaut, has been replaced by an alien double in league with the Soviets. At least I think so; it was quite difficult to follow the plot, with a densely written sex scene every couple of pages. (And yet the sex doesn’t have a lot of variety – I counted precisely one blow-job, quite close to the end, and there’s one scene of girl-on-girl action in the middle.) The kindest thing to say is that it has not aged well. But you can get it here.

I bet that Richmond’s other books of the time, billed as autobiographical (Fiona, Story of I, On the Road, The Good, the Bad and the Beautiful) are just as fictional. I won’t especially be looking out for them.

This was the shortest unread book I acquired in 2016, at Eastercon where I’m always on the lookout for women authors who I haven’t previously read. Next on that pile, continuing the theme perhaps, is The Shape of Sex to Come, ed. Douglas Hill.
