Another interesting point about this book is that, while Alex is introduced as a very detestable character, I do insist that you don't give up on the book at the start. You probably will get annoyed/bored with reading all about the bad crimes that Alex commits, but about half way through Alex is capture and gradually becomes more and more likeable, and then an interesting philosophical question is asked: Is it better to choose to be bad than to be forced to be good? I shan't tell you how it's answered!
Despite dealing with rather uncomfortable subjects, I still liked this book, so I rate it as a 7.4/10.
