The ghost series should never have existed, John Ringo would be one of the first to tell you that. He wrote it because the story was distracting him from what he needed to work on, and then mentioned it online in an offhand manner, and his fans insisted on him publishing it, and his publisher refused to let him use a pseudonym.
Doctor McNinja was around before Doctors Fucking, so the other doctor is a clone of him, but without the awesomeness.
He isn't as badass as McNinja, but how 'bout Inspector Tequila?
