"John Returns" continues the story that tells how John Harris leads a group of survivors through the chaos of a country that has fallen apart. The US President and a coalition of third world leaders have launched a major nuclear and EMP attack on all of the major powers and killed over 100 million Americans. The Grid is down and most cars and trucks won’t run. All electronics were destroyed with the EMP blasts. The USA is in chaos with criminals and thugs attacking innocent citizens, while John and his team fight the corrupt Department of Homeland Security and the President. John Harris leads the people from a major part of the old USA and most of the remaining US military in building a new country, the Independent States of America. The USA immediately begins attacking the new country along with attacks from drug lords based in Mexico. In the last book, Apocalypse in the Homeland, John has survived being kidnapped twice, a plane crash and several battles as he fights to get home after his plane crashed in Wyoming. The ISA has sent Scott Harris and a small army to find his father, John Harris, the President of the ISA. John has plans of his own and is almost home when he hears of a devastating attack on his home base. John is a tough man, but is this the last straw?
