It is ironic that the book I have enjoyed the most (among those read so far) from The Culture does not contain elements of science fiction, except in a certain part of the book that cannot be talked about to avoid revealing the mystery to future readers. It has been refreshing to encounter the best of Banks after the slight disappointment that was 'Excession', the previous book of The Culture. 'Inversions' is a more literary novel, far from all the paraphernalia and pyrotechnics typical of space-opera, of those grandiose scenarios and ships. Therefore, it is an epic fantasy book, but not fantasy as usual (after all we are talking about Banks), but a story in which one has to pay very close attention to the details, since a parallel is made with our society (and not for the better; the "skirmishes" between Cromwell's England and Louis XIV's France come to my mind).
The story is actually two, which at one point seem not to be related, until at the end they do seem to have a point of union. On the one hand we have the part of The Doctor, in which the protagonist is the doctor of the king of Haspide, and her assistant Oelph, the narrator and at the same time spy on the actions of the doctor. She is a curious woman, a foreigner, who seems to have remedies for everything, and what is worse, her own ideas, something that does not go down too well within the court. Everything that happens is told from the point of view of Oelph, which causes a certain strangeness in some situations. It is delicious to witness his descriptions of places and characters that cross his path.
On the other hand, we have the second story, that of The Bodyguard, set in another city of the same world, and starring DeWar, the bodyguard of the Protector, King UrLeyn of Tassasen. This story is told by an omniscient narrator, although it is a text that will later let us know Oelph. DeWar, using the means at his disposal, dedicates himself to saving his king from the various assassination attempts he suffers, although it costs him a lot to convince UrLeyn of the convenience of his protection each time. An important character in this story is Perrund, one of the king's concubines, who was left with a disabled arm when trying to save him. Some of the best moments of this part are those lived by DeWar and Perrund during their conversations while walking or playing various board games.
The best thing about the novel are the characters, with whom you live and suffer equally. They have their own soul. You come to empathize so much with them that at the end of the last page, you know that you will remember them for a long time. Banks was one of the best writers inside and outside the genre, both for his descriptions and for the emotions that he is able to convey with his careful prose.
