If you like unreliable narration and rug pulls Nick Harkaway's novel 'The Gone-Away World' really takes the cake (and is brilliant)

I enjoyed Gnomon, but boy I didn't find it an easy read

The second and third times through get easier, once you can appreciate the patterns and links that seem extraneous and confusing at first. Totally different kind of book, but I’d put it up with Infinite Jest as far as being convoluted but incredibly rewarding. And of course more SD / tech focused.

Thank you. I'll give it another go. I did enjoy Angelmaker as an enjoyable romp
