This was an interesting book, but it is, perhaps, hard to untangle those facets that make it interesting as a hybrid fantasy novel (with some elements of science fiction; I have heard the genre described as a ‘silkpunk’) with its sexual character, which is entangled with the author’s non-binary sexual identity. Characters are genderless until they make a decision (which, it seems, usually occurs in the late teens or very early twenties) to choose it and then there is some sorcery (the term used is ‘slackcraft,’ the ‘Slack’ being an all pervasive something that rather resembles the Force). The main characters are twins who choose different genders and different paths (one becomes a revolutionary, associated with a group that seeks to use technology to give the ordinary people more power, making them less dependent on ‘slackcraft’ practitioners, known as Tensors; the other marries an abbot, which, I guess, is ok in this world). The society is also matriarchal.
I am torn on this. I enjoyed it, but did I enjoy it enough to read more in the Tensorate series?
