I know this is a bit older (1997), but I really enjoyed reading it for my contemporary Latino lit class. Díaz is quickly becoming a favorite of mine.
Díaz forces you to consider what it means to be a man, an immigrant, a son, a friend, and all the rest. It’s a short story collection, I think it’s best read in pieces so you aren’t overwhelmed, or confused. It’s a pretty good read if you want a short story that will make you think for the whole day. Díaz writes in a minimalist style that leaves you (the reader) to fill in the blanks. A neopicaresque that you need to own.
