Read a novel in English

Friends,
I need to share with you how difficult is reading a modern novel in English. Special when the author wants to show or explain emotion and conversation in “Speaking English” or “colloquial speech”. He used a lot of slang that are not familiar to me. Before I stated read this book I had been read a novel by Sidney Sheldon and this author used a formal English and this book became more easer to me that our novel. But, despite all difficulties, I like some much read and this novel is good and has a beautiful message.
