Finished this book. It was really interesting: intricate story, memorable characters, nice ending and so on.
Listening to the Spanish audio book while reading English text is really useful. I learned a lot of new words and phrases. Also i was able to notice flaws in translation: errors in certain phrases, missing sentences, misinterpretations and others mistakes. I hope one day to read this novel again and in Spanish.
In the following week I am going to try read newspapers. I have already tried it - rather difficult, but definitely not impossible.
