Maybe the new 'To kill a mocking bird'

This book has had and continues to have a huge success in the United States. Yet I hesitated to buy it, saying that the issue had already been discussed many times, and finally I started and do not regret one second.
We already know history, we already know the context and yet this book offers more: the style of the author, 'witty', tinged with irony, the book's characters and not just the main, deep, funny, strong which (women are honored in this novel) we attach. The end is not unexpected and yet I did not let the book of the weekend.
One thing bothered me, however, the accumulation of clichés of the American black community (where is it justified?) But does not stop me from loving this book.
