Three Guns by Dominic L Dotson

Step into the tattered boots of the last Gunfighter in this post-apocalyptic saga of how the previous world ended and the After became reality. Nothing is as it was in the Before, and the world that Three Guns travels through is a macabre reflection of current times and what could be our future. Through a trail of hardship, loss, and incessant violence Three Guns uncovers modern society's dependencies and failings while longing for the life he never had and teetering on the edge of sanity.
The hard hitting prose, written by a US Marine infantryman who is a veteran of America's War against the Taliban in Afghanistan, takes readers on a journey that is as thrilling as it is violent. Three Guns struggles with many of the same issues that today's veterans face and is as much at war with himself as he is with all the dangerous inhabitants of the world of tomorrow that he walks in. Three Guns' story is a cunning critique of humanity's growing dependence on technology and the advent of artificial intelligence that is sure to surprise and enrapture any who are willing to join him on his quest for answers.
