I'm not too big a reader but I would recommend the Quarantine series by Lex Thomas: https://www.goodreads.com/series/73934-quarantine It contains a lot of carnage and death. Just a heads up. If you want something sweeter you can check out this teenage/romance/tragedy book "The Fault in Our Stars." Warning: this one gets sad. http://www.goodreads.com/book/show/11870085-the-fault-in-our-stars "I am Not a Serial Killer" is another read I enjoyed. Kinda made me go crazy while reading it and was just an all around nice "thriller-horror" book. http://www.goodreads.com/book/show/7617119-i-am-not-a-serial-killer Now, I wish I was more of an avid reader so I could recommend you more but, alas, I'm not. Could you recommend me some books in Spanish?

Leaving Time” by Jodi Picoult can be nice addition to your learning set of books.
