Book excerpt: Romulus Ledbetter wasn't always homeless. He once was a devoted husband, father, and musician with a bright future. He now forages for food in the trash cans of the city's better neighborhoods and wages a strenuous one-man war against Cornelius Gould Stuyvesant, an evil -- and imaginary -- power broker who is responsible for society's ills, as well as the sinister Y- and Z-rays that are corrupting humankind. Then one wintry night, Rom finds a corpse at the mouth of his cave that rouses his well-defined sense of ethics and launches him on an obsessive quest for answers. Forced to reconnect with society, Rom leaves his world and journeys through a spiraling web of clues and hunches, straight into a sinister den of money, temptation, and murder--otherwise known as the "civilized" world.
