Lois McMaster Bujold 
<span>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.</span><p>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?</p><p>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.</p>
