Query: A MODERN MUST READ

Very few books these days become must reads in the sense that everyone is talking about them and so you must read them to know what everyone is talking about. As you can see from the reviews here, this is one of those must reads. I won't go into what the books about because everyone else has, but I can say I've read the book twice and told friends they should too.
