This is not a simple book, if you couldn't figure that out from the prior two paragraphs, and the book enjoys tossing out long diatribes and explanations about the worlds it is describing. And yet each of these narratives is developed pretty well, despite having to share the book with the others. Then there are two narratives in what are basically our modern day world, one in Ancient Carthage, and one from a different future.

The main narrative, featuring the character who's going through the other four narratives, is in a near future dystopian London where all of London is watched by a set of cameras and microphones.

Gnomon is a book that features no less than five narratives - all with fantastical or science fiction elements, and it's never quite clear until the end what exactly is really going on. And yet those comparisons don't really do Gnomon justice. The closest comparison I can think of - and I admit to seeing this comparison in another review - is Inception.maybe if it was combined with The Three Body Problem. It's also one of the most unusual and unique books I've ever read. Short Review (cont): When a woman dies in a routine interrogation in a Future surveillance state London, Inspector Nieth dives into the woman's memories only to find the stories of 4 others inside.& hints of trouble in the outside world.
