SF series Looking for an SF series I read as a teenager. Don't remember a lot of details. Earthlings live in space on giant ships and fight an alien species who could pass for humans with blue? hair except they're giants. Then at some point some of the aliens infiltrate the human ships. It sounds really weird when I type it all down like that. Nevertheless, anyone recognize it?
