Valor In The Ashes [EPUB ebook] 

A decade has passed since the nuclear nightmare of the Great War that brought America to the brink of destruction. Out of the smoldering ashes, Ben Raines has emerged to build a new society in the once proud land. But in this hellish new world there are devils among men who will stop at nothing to destroy the dream of a new America. Leaving a small rear-guard detachment at their home base in Louisiana, Ben Raines and his rebel army begin an overland expedition to New York City–the armed citadel of the cannibalistic mutants known as the Night People. For Raines and his rebels, it means clearing skyscrapers floor by floor and stalking endless labyrinth of underground tunnels-a perilous search-and-destroy mission that will decide the fate of freedom’s cause.
