This dissertation presents a thematic study of the novels of John Nichols. Intended as an introduction to his major works of fiction, this study discusses the central themes and prominent characteristics of his seven novels and considers the impact of the Southwest on his work. Chapter One presents biographical information about Nichols, focusing on his political awakening and subsequent move to Taos, New Mexico. A visit to Guatemala, after the publication of The Sterile Cuckoo. his first novel, brought Nichols to a realization that America was not a benevolent world power. He began to consider capitalism a voracious, destructive economic system, a view which informed the subjects and themes of his five novels written after The Wizard of Loneliness. In 1969, Nichols left New York City, moving to Taos, New Mexico, an area with a history of physical and economic aggression against its predominantly Native American and Hispanic population. The five polemical novels, all set in northern New Mexico, were written after this move. Chapters Two through Four discuss Nichols's seven novels, analyzing theme and reviewing critical response. /V Chapter Two discusses The Sterile Cuckoo (1965) and The Wizard of Loneliness (1966), novels written prior to Nichols's political awakening. Both of these books are rite-of-passage novels which focus on relationships. Chapter Three analyzes The New Mexico Trilogy: The Milagro Beanfield War (1974), The Magic Journey (1978), and The Nirvana Blues (1981). These three novels depict the exploitation of people, the displacement of cultures, and the despoliation of land in the name of progress. Chapter Four considers A Ghost in the Music (1979) and American Blood (1987). Although these two books differ greatly in tone and subject, they are similar in the general theme of waste--waste of human potential and human life. Chapter Five identifies the prominent characteristics and reviews the major themes of Nichols's novels. It concludes with a discussion of the impact of the Southwest on Nichols and his literature.
