I'm making my way through the Strugastky brothers' works, found out about them through roadside picnic but i just finished "Monday starts on Saturday" and enjoyed it just as much.
Edit to add: it's a science fiction novel from the perspective of a soviet programmer who stumbles into magic. He meets a lot of people for whom magic is mundane, and the book does such an awesome job describing his confusion and curiosity vs everybody elses acceptance of it as day-to-day. Its also super funny :)
I'm going to go back a few books and say Stalking the Wild Pendulum, simply because it's so out there and weird while still feeling vaguely plausible, maybe?
I'm glad someone found it interesting! It's a wild ride. He was an interesting dude. Somewhere between a quack and a genius. I just found it a refreshing change of pace from the standard fiction/non-fiction tropes.
