Book excerpt: Scientist Charles Neumann loses a leg in an industrial accident. It's not a tragedy. It's an opportunity. Charlie always thought his body could be better. He begins to explore a few ideas. To build parts. Better parts. Prosthetist Lola Shanks loves a good artificial limb. In Charlie, she sees a man on his way to becoming artificial everything. But others see a madman. Or a product. Or a weapon. A story for the age of pervasive technology, Machine Man is a gruesomely funny unraveling of one man's quest for ultimate self-improvement.
