On the fiction side, just read The Secret History of Costaguana, by Juan Gabriel Vásquez. If you're familiar with Nostromo, by Joseph Conrad, this is set in Colombia, the country that inspired his own fictional Costaguana. Even if you aren't familiar with Conrad's work, it's worth the read. Some of the best historical fiction I've ever read. I learned more Colombian history from that book than I ever would have learned in my history courses. Of course I read the english translation, but my knowledge of Spanish has all but vanished since high school.
