The Savage Detectives
Roberto Bolaño
The structure of this was very interesting: part diary, part collections of interviews. It jumps backwards and forwards in time, and almost demands a second reading after you know what happens in the pivotal section (which is, of course, at the end).
The actual content was less interesting to me than the structure. It focuses on a poetic movement in Mexico, and on a few characters involved in its creation.
It was interesting to be reading about Mexico while I was there. I learned at least one piece of slang from it that was actually being used around me.
