This book takes some of the tropes from early feminist sci-fi (women only or matriarchal) and pulls it into the near present, in an era of #metoo and consent. The central character has been sent to The Fortress after his wife catches him cheating, again, and must submit to whatever happens there. In his former life he was a high powered executive so it is quite the change. I read it in a day and was uncomfortable and delighted simultaneously.
