Read this. Cordwainer Smith is timeless. - Terry Pratchett. Smith's instrumentality is the most complex and lyrical of all future histories, redolent with future antiquity. It is a history of a mankind transformed, oddly convincingly, by a relentless series of changes - war, genetic engineering, interstellar travel, immortality - and Smith's remarkable, rich prose gives shivery hints of a darkly imagined universe extending far beyond the boundaries of the stories. Lush, strange, unique, a treasure. - Stephen Baxter.
