I have a book report on "A Clockwork Orange" due tomorrow and i havnt read and dont own a copy. Help? - cheaters movie online

I saw the movie, but I know there are differences between the two. I would at least go through the book so that he can in what I do not know the film to fill. I do not consider myself a cheat and does not want to use SparkNotes or something similar. Does anybody know where I can find an online version of the book?
