His cousin J. A. Johnstone writes most of his books now, or ‘co-author’s’ them at least. Most William W Johnstone books released after 2006 are co-authored by J. A., but it seems they use his name mainly for marketing and attracting his fans. There is little explanation for whether they were originally William's ideas being executed by J.A., or if they are the former’s own ideas. All the novels listed here are only authored by William.
