“Tumbleweed Underworld offers a rare and deeply human history of addiction in the nineteenth-century American West. Centering the life of Georgie Clifford, a sex worker and morphine addict, Pagán uncovers how misogyny, violence, and medical uncertainty shaped women’s lives and choices in a volatile frontier society. The result is a haunting portrait of life on the margins.”―Jacqueline D. Antonovich, Muhlenberg College “Excellent history and excellent storytelling…Pagán’s incredible sleuthing allows him to follow Minnie’s/Georgie’s tortuous younger years along with those whom she encountered, wedded, bedded, and befriended, who, in turn, often abused her and certainly almost always fed her addictions, as she amazingly always moved forward and hoped for better.”―Sarah Deutsch, Professor of History Emerita, Duke University
