It's possible that:
* There is a typo in the name. Could it be a different spelling, such as G.E.M. Skues or G.M.E. Skues?
* The author is not widely known. Perhaps they are a relatively new or obscure author.
* The author uses a pen name. Could the name "G E M Skues" be a pseudonym?
To help me find the author you're looking for, could you please provide any additional information you have, such as:
* The genre of books they write.
* Any specific book titles you know.
* Any other details about the author, like their nationality or approximate time period of writing.
With more information, I'll be able to help you find the right author.
