Before retiring in late 2004 John A. Miller, Jr. had worked for more than forty years in the fields of computers and telecommunications at several major corporations and universities. However, he always had a desire to write, so armed with a new computer in 1991 he sat down and began writing his first novel, Pima. which was published as a paperback several years later. Over the years John has continued writing as a sideline. Because he had lived in southern Arizona for a total of nearly ten years, first while serving in the U.S. Army in the mid-1960s and later while working for a Government contractor and then a private corporation, John decided to set his Pima series of novels in an area he knew well, the mountains and deserts of Arizona. Later short stories and novels are set in other locales. Now John makes his home in eastern Pennsylvania, the area where he grew up.
