While the book does present problems it doesn't really answer, (such as, why is everyone ok with living in a virtual world that acts as a drug to stave off their horrible everyday lives and what could happen if the game suddenly was destroyed or the fact that what if the worlds crappy condition is partially due to the majority of the human population caring more about a virtual world?) other then those its a pretty decent book to be categorized as YA (I'm sorry, but most young adult books are the same formula over and over again.) The characters may not be the best, but the sheer amount of work Ernest Cline put into creating a living breathing (albeit paper) VR world is amazing. The book is basically a celebration of the future of games (which is scary) and of the origins of games. The book did have some questionable materiel though, violence wasn't much of a problem, most of it was virtual. As for language, there is a fair deal, several F-bombs, but overall, considering its based on a VR world where gamers can chat openly, its incredibly mild (I'm looking at you Call of Duty chat) The book is also very funny, but not overly so. There is some inappropriate content, maybe a paragraph to skip, but its still fairly mild considering its online chat. One charterer (SPOILER?) is eventually found to be a lesbian, so, yah..... Overall, this book was just fun, I didn't really think it had any deep messages (except big corporations are evil and the 80's was amazing) but if your just looking for a fun book, I would highly recommend this one.
