According to John, "Edge of Heaven" is the first in a post-apocalyptic series of six novels.
Each signed and numbered first edition copy includes a sample of the author's DNA on the signature page. This figures prominently in the fifth book in the series, "John-Tar," in which a 21st century sci-fi author's DNA is grown into an avatar in the 28th century.
The book is available at bookstores in Laramie, Cheyenne and Jackson in Wyoming and Fort Collins, Colo. Find out more about "Edge of Heaven" at http://www.edgeofheavenbook.com/
