Book excerpt: Channelling the turbulent period of the Vietnam War and its ruthless pitting of ideologies, cultures, generations, and races against each other, military historian and acclaimed fantasy writer Chris Evans takes a daring new approach to the traditional world of sword and sorcery by thrusting it into a maelstrom of racial animus, drug use, rebellion, and a growing war that seems at once unwinnable and with no end in sight. In this thrilling epic, right and wrong, country and honor, freedom and sacrifice are all put to the ultimate test in the heart of a dark, bloody, otherworldly jungle. In this strange, new world deep among the shadows under a triple-canopy jungle and plagued by dangers real and imagined, soldiers strive to fulfill a mission they don't understand and are ill-equipped to carry out. And high above them, the heavy rush of wings slashing through the humid air herald a coming wave of death and destruction, and just possibly, salvation.
