I started
A Canticle for Liebowitz last night and got through the first act (out of 3 I think).
The end of the first act left me completely stunned and I had no desire to read on anymore.
I don't want to spoil it, but I'm sure a lot of you know what I'm referring to. I'm not a heavy reader, but I do t think I've ever read a book that used that specific plot technique before.
Spoilers for what I'm talking about below.
