This book is amazing! I loved it, as I often do with Green's work. Me, my 15 year old, and 17 year old twins all read it in middle school, and they all had very expressive opinions on the book! My 15 year old, thought the book was, in his words, 'fucking perfect', and 'represented teens across the country'; this is, in fact, his favourite book, now! However, both of my twins, Perry and Alfie, thought this was 'shit', and 'a total waste of fucking time'. Parents can expect there to be slightly graphic areas in the book, such as, a lot of talk about porn, a girl performing a blowjob on the boy, frequent swearing, and a lot of smoking/drinking. In my opinion, however, this merely represents every-day-life, amongst teens. Quite frankly, if you are against this work of art, and don't want your children to read this, then don't let them, and go fuck yourself. I highly recommend this, to 10+, it is a bloody great read!
