John began writing shortly after the March 28, 1979 Three Mile Island nuclear plant incident in Pennsylvania when one of the plant’s reactors suffered a partial meltdown. The slim book, Three Mile Island: A Time of Fear, was the first book to be published about the accident and was circulated worldwide. Shortly after that he edited and re-wrote Deadly Pursuit, a non-fiction book by noted Pulitzer Prize Journalist Robert Cox. A TV show based on the true events of this story aired on ABC in the mid 1980s. Since then, John has written two works of fiction: Cloudland, and The Borshov Effect.
