I know nothing about Puerto Rico. There's a chance we may go on vacation there. Generally, I try to read a book or two written by a native author before or during my trip to a new place. For Puerto Rico, there doesn't seem to be a go-to history or work of fiction that makes people say, "if you have to read one book, it should be this one." I suspect my lack of Spanish googlefoo is holding me back, but then again, if it's not at a 4th grade level, I can't read it in Spanish anyways, so perhaps I'm not missing out.
