Recently I've finished listening to this great audio-book by Anthony Burgess. I've challenged myself to listen this book in English and happy to say that I've successfully managed to do it.
I think it was some kind of cheating for me, because my first language is Russian and the author in this book used quite a lot Russian words as part of new English language called "Nadsat". Droogs, moloko and vek I think were used more frequently than others.
Reading the book I couldn't stop comparing it with Stanley Kubrick movie. Pictures from the movie constantly continued appearing behind my eyes and I must admit movie was shoot pretty close to the book, maybe except the final.
Also in the movie main characters are older. In the book they are 15 years old in the begging and when you see Malcolm MacDowell, well you just cannot say that he is 15 years old, but it's not a big problem.
