Your experience echoes mine! It was my least favourite Culture book precisely because of the setting making it feel more like fantasy. But when I reread all Bank's work I also found I appreciated it more second time around. It's still not in contention for favourite but I definitely enjoyed it more.I finished the audiobook of Inversions by Iain M. Banks. The pre industrial setting made this my least liked Culture book when I read it, but listening to it has made me appreciate it a lot more. It’s actually quite a lovely and a subtle book.
I’m not sure what to get next. I think it’ll be Banks’s The Algebraist. By all accounts, quite a complex book.
