Lots of great recommendations on this page! Alvaro Enrigue is right up my alley. I'll probably be picking up Sudden Death real soon. The Vegetarian sounds incredible, too. I did the opposite from the protagonist last summer and started eating meat again after being a vegetarian for 8 years (which wasn't exactly met with joy by some of my "progressive" friends either), so the topic hits kinda close to home... albeit in a very different, and definitely less tragic way.
I loved The Emigrants and Sebald's writing in general. It's grim and sad, but in a beautiful way. I bought a copy of Austerlitz at a second-hand store the other day and will pick it up soon.
Nazi Literature in the Americas is a strange little book. And I mean that in the best way possible. It's typically Bolano, but totally unlike everything else I've ever read.
Speaking of Bolano, I still haven't finished 2666... I don't know, I was really busy for a while and had to lay off reading for a while. I really like 2666 though. It's Bolano's bleakest work by far (which says something) and it's very different from, let's say, The Savage Detectives, but it's still quintessentially Bolano. I'm almost done with the infamous "Part about the Crimes", which details every single femicide in a fictionalized version of Cd. Juarez, but I'm not as repulsed as some readers have been. It's cruel, it's brutal, but it's hardly worse than Blood Meridian, for example. At this point, 2666 seems to circle around certain themes, some of them concrete - such as female homicides and chauvinism in Mexico - and others more abstract - like lunacy and evil. A recurring motif are abysses. It's very dark, it's very complex, but it's not a Pynchon or DFW novel, where every detail matters. Rather, it seems to be more about atmosphere (if that makes sense).
