What has the author Charles Gordon Cooper written?

There is no widely known author named Charles Gordon Cooper. It's possible there are lesser-known authors with that name, but without more information, it's impossible to say what they may have written.

It's also possible you're thinking of Gordon Cooper, a famous American astronaut who flew on the Mercury 9 mission. He did not publish any books under his own name, but he did contribute to a few publications about space exploration.

Could you clarify your question? Perhaps you can provide:

* Full name: Is there a middle name or any other distinguishing features?

* Genre: What kind of books do you think this author might write?

* Any other clues: Do you remember anything else about the author or their work?
