As American capitalism undergoes a seismic shift, Michael Lewis, author of the bestselling Liar"s Poker, sets out on a Silicon Valley safari to find the true representative of the coming economic age. All roads lead to Jim Clark, the man who rewrote the rules of American capitalism as the founder of (so far) three multi-billion dollar companies--Silicon Graphics, Netscape, and Healtheon. Lewis"s shrewd, often brilliantly funny, narrative provides ahead-of-the-curve observations about the Internet explosion and how the success of Silicon Valley companies is forcing a reassessment of traditional Wall-Street business models. Weaving Clark"s story together with that of this new business phenomenon, Lewis has drawn us a map of markets and free enterprise in the twenty-first century and blown the lid off the changing economy.
