Title: Among Sheffield's best work
Review: At his best, Sheffield fits in the category with Larry Niven in that Sheffield is able to deliver a fully developed world driven by several far-sighted predictions of where technology and need will drive mankind. Sheffield seems to produce his very best material when he writes solo and (frankly) when he writing 20 years ago."Sight of Proteus" fits both those parameters, and in my opinion is among the two or three best that Sheffield ever produced. The story is based in a world where changes to the human form can be ordered from a public catalog - and of course the darker underworld where prohibited changes can be obtained.In an over-populated world where underground scientists are willing to push the envelope of human form and evolution, this novel broke new ground pushing the "what if?" question related to human potential. I have the paperback in its 1978 edition and it has a permanent place in my SF collection.
