Enjoy video games? Enjoy fiction? You will definitely want both of these books on your list if you answer "yes" to both questions (and even if you don't!). After reading the books, watch the movie for book one also. Hopefully a movie comes out for book two!
There are a lot of pop culture references, many that I did not understand, but they do not downplay the fun of the book. The book is exciting, and the voice (for those of you choosing audio book) will sound familiar to those of you who have watched Big Bang Theory or Star Trek. Highly recommend both books!
