Mark K. Roberts was born in Kansas, USA. As a child he loved reading adventure books and going to the movies on Saturday afternoon to watch Westerns with his great friend, Patrick E. Andrews. His family moved out to Dan Diego, California where he later served in the California National Guard. He had some success in co-writing The Penetrator series with Pinnacle Books under the name of Lionel Derek. Many years later he and Patrick brought up the subject of writing westerns together and the result was APACHE GOLD.
Apache Chief Halcon burned with a fierce hatred for the US Pony Soldiers, vowing to take the scalp of every round-eye in the territory. When gold is discovered on Apache land and an army of bloodthirsty prospectors surround the Indian village, it’s Halcon’s revenge against blood-crazed greed. O’Callan's troopers must ride to glory or death for peace on the new frontier
