Not many books have a mechanical engineering type as the main character. Then again, not many people have 4 hands. I've re-read this book several times, and still like it. One of those books that aren't likely to be on my posted bookshelf, since I want to keep it.
Leo Graf was just your average highly efficient engineer: mind your own business, fix what's wrong and move on tothe next job. Everything neat and according to spec, just the way he liked it. But all that changed on his assignment to the Cay Habitat. Could you just stand there and allow the exploitation of hundreds of helpless children merely to enhance the bottom line of a hearltess mega corporation?
Leo Graft adopted 1000 quaddies--now all he had to do was teach to them to be free.
