Falling Free by Lois McMaster Bujold

Leo Graf was just your average highly efficient engineer: mind your own business, fix what''s wrong, and move on to the next job. But all that changed on his assignment to the Cay Habitat, where a group of humanoids had been secretly, commercially bioengineered for working in free fall. Could he just stand there and allow the exploitation of hundreds of helpless children merely to enhance the bottom line of a heartless mega-corporation? He hadn''t anticipated a situation where the right thing to do was neither safe, nor in the rules. Leo adopted a thousand quaddies. Now all he had to do was teach them to be free.
