Machine Man [EPUB ebook] 

When 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. His employer, military contractor Better Future, has the resources he needs to explore a few ideas. So he begins to build parts. Better parts. Charlie’s prosthetist, Lola, is impressed by his artificial limbs. But some see him as a madman. Others, a product. Or even a weapon. Existing at the intersection between mind and body, in the dawn of the age of pervasive technology, Machine Man is a gruesomely funny tale about one man’s quest for the ultimate in self-improvement.
