Some strange things happen when being almost the only iberoamerican in a forum. One is reading this thread and seeing that the only (literary) authors I read in common with the rest, which I assume are mostly from Europe and non-latin America, are the Russians (although the only one I really like is Dostoievski). I also like Kafka which I assume is known everywhere as well.
I assume probably also some classics they forced me to read in highschool such as Shakespeare (translated, there is no way I can read it in the original, even now) or Poe, but I would not read them for pleasure.
Anyway, I can recommend some books you probably don't know. Saramago (portuguese author) is my all-time favorite. My favorite book is Galeano's "Open veins of latin america" (which I know has been translated to English). If you are not convinced that today's problems in LA can be traced back to Spanish and Portuguese invasions (it does not really cover the small Caribbean nations with French or Dutch colonization history) read it. I must warn you, it is a tough read. From Argentina, I love Cortazar, although his writing is focused on language more than on history, so I don't know how well it translates into other languanges, if there is such translation available.
As for current readings, I guess I have not read a single fictional book in 2013. Between scientific papers and newspapers, I don't want to read a single additional paragraph. I have recently read "thesis draft" volumes 1 to 12 at this point. I expect 2 or 3 more sequels of that one. They say the last is the only one really worth reading, but I am the kind of person that goes through series in order.
