Book excerpt: Nobody blows smoke like Nick Naylor. He's a spokesman for the Academy of Tobacco Studies-in other words, a flack for cigarette companies, paid to promote their product on talk and news shows. The problem? He's so good at his job, so effortlessly unethical, that he's become a target for both anti-tobacco terrorists and for the FBI. In a country where half the people want to outlaw pleasure and the other want to sell you a disease, what will become of the original Puff Daddy?
