This was a very well, if strangely, written book. I had a really hard time understanding alot of the Spanish words that were thrown in there. Most of the I got from reading them in context, but I was never 100% sure I got the right meaning. I loved the nerdy Oscar, and the self-assured Lola. I couldn't figure out the narrator till about 2/3 of the way through (he called himself 'the Watcher", so i didn't realize he was one of the characters), and that was a little unnerving.
Overall, the history lessons (were they true?) were fascinating. The characters were believable, and the story was real. I really liked it. It was a bit 'angry', which is cool with me, considering the story, but some book clubs might find the language offensive.
