Introducing a modern novel

Can you please introduce a novel to me in which I can find lots of English daily short and long conversations, and It is written in years after 2000? When I search in bookstores of my country, I find books that are either quite old or very literary e.g. Wuthering Heights, Robinson Crusoe, Sherlock Holmes, 2000 Leagues Under The Sea!! I am tired of reading sentences like: What shall we do now!?!? But I feel I need something more modern and also consisting of more various conversational statements. I have a sufficient knowledge of English vocabulary however, it doesn't benefit me that much most of the times and I rather need sentences than words.
Recommendations?
