From the back of the book: "What is 'human'? In the year 2100, humanity faces its greatest challenge: settling the vast reaches of the solar system. Spacegoing transnationals develop technologies that governments fear to explore, while bizarre posthuman cultures bloom like exotic flowers. Will 'human' cease to have any meaning in a world of genetic engineering and digital consciousness? It is a time of wealth and adventure, of transformation and terror - the age of Transhuman Space! Transhuman Space is the first in a comprehensive line of sourcebooks exploring a transhuman vision of the 22nd century, where biology and nanotechnology merge with interplanetary adventure."
