The Mystical Guatemalan Robes — David Polansky

A ruthless, sixteenth-century pedophile monk is granted immortality by a mysterious robed sect secluded in the highlands of Guatemala. He carves a tortuous, secretive path forward in time until he is discovered by a troubled airline pilot suffering from post-traumatic stress disorder. Pilot and priest engage in a holy war only to discover that both share a painful, common past. The winner in this epoch battle carries the fate of humanity in his palms. Victory or defeat may well rest in the secrets and power of a single robe.
