Why CS?

Why C.S.?
NO, it's not because my favorite author is a CS.

Above is the copy of the book as it was supposed to look. The author's name is Charles S.(my pen initial, not my real one) Areson is right where it is supposed to be.  

However, I was in a hurry signing up with the publisher, I only put my initials thinking I could change it. I found out that what you place in that section has to be what is on the book cover. You could not go back and change it.

 Oh!

I did not want to redo the entire project, so I just went with it. To be consistent, I have decided that all of my books will carry the name.

The mystery is solved!?

So what does the "S" stand for?

Come on, I'm an author, I need some secrets. ;)
