Natalie Angier, the masterly Pulitzer Prize-winning journalist, describes a world few lay people have ever seen, in a book Edward O. Wilson called 'the debut of one of the few really first-rate writers in science.' Investigating some of the great breakthroughs in recent biology, involving the cloning and deciphering of the genes that control susceptibility or resistance to cancer, Angier explores a richly human community that pursues science with near-romantic intensity. Here a special breed of men and women, in whom the desire to know the truth burns like an obsession, follow science for the betterment of the human condition, personal competitive reasons, and the sheer joy of the hunt.
