- "Before a devastating orbital strike crippled it's government and setted the stage for invasion, the United States Military relied on a top-secret unit of special operatives that are known only by their codename: The Ghosts. But, when their leader and commanding officer, Captain Gabriel Rorke was captured deep in South America at the hands of the Federation, it was his place atop the highly-trained, off-books unit that made him the highest-priority enemy combatant in American history. Exclusively published on Kindle and the Kindle devices, "Devil's Breath" buried the readers underground with Rorke as he struggled to survive the years of captivity and was a victim of not only the chemical, psychological and physical torture methods that are perfected by the CIA, but the ancient Amazonian methods of coercion that was fused by the Federation forces with one goal in mind: Reprogram America's greatest weapon into it's greatest threat."
