I decided this year to work through some SF Masterworks I had missed along the way and this was the first I picked to try.
I am afraid this one didn't really work for me. It is deliberately opaque, told in a Burroughs-esque style that makes it very difficult to follow. It jumps all over the place in it's timeline with some parts not being clearly signposted as to where they fit. It also jumps PoV very often and none of the PoV characters are very relatable imo.
The main plot driver is only revealed in the last chapter with no organic grounding previous to that setting up the big reveal.
I did finish this, out of curiosity and a certain bloody mindedness and some parts are well executed. Thus, three stars. I don't think this is necessarily an objectively bad book, it wouldn't be a Masterwork if it was, it just made some choices that didn't work for me.
Cannot recommend though and I won't be finishing the series.
