I have four books available: A Subtle Armageddon, Michael's Story, David Gideon, and Triumph of the Ignorant. They are available through Amazon or you favorite bookstore.
I remind you of this in part because it's the shameless self promotion I'm told I need (although, honestly, I am very uncomfortable with it), but also as the Amazon links herein offer books by one Charles Martin. I have nothing against him, but I am Charles Martin Cosgriff. The links on my page in themselves will not direct you to my writings. We are working to change that. But until them, I'm not that guy!
