I really enjoyed "Heart of Darkness" so I thought I'd read something else by Joseph Conrad and Nostromo is widely considered one of his finest novels.
It took me a while to get into the book, and it took me a long time to finish it, but I still enjoyed it. Tales of heroics are layered on top of the efforts of one rich and powerful European man (Gould) fighting against the corruption of various governments in a fictional South American country (which happens to closely resemble Columbia).
Greed is rampant and swirls around Gould constantly as he is the owner of a very productive silver mine. To me the book seems to be a criticism of European imperialist policies as there are many attempts by Gould and his peers to impose order on the indigenous people much in the same way the western world today tries to impose democracy in places like Iraq and Afghanistan. Their failures are many and the costs of their successes are high.
Anyway, it's a good book, but a lot of work as it is easy to lose track of what is going on if you're not diligent in your reading. I feel like I should read it again someday over a shorter time frame and with greater focus.
