In the late nineteenth century, Sioux Falls, South Dakota, offered a tempting freedom often difficult to obtain elsewhere: divorce. With the laxest divorce laws in the country, five railroad lines, and the finest hotel for hundreds of miles, the small city became The Divorce Colony-- the unexpected headquarters for unhappy spouses, and the center of a heated national debate over the future of American marriage. White unveils the incredible social, political, and personal dramas that unfolded in Sioux Falls and reverberated around the country through the stories of four very different women: Maggie De Stuers, a descendant of the influential New York Astors whose divorce captivated the world; Mary Nevins Blaine, a daughter-in-law to a presidential hopeful with a vendetta against her meddling mother-in-law; Blanche Molineux, an aspiring actress escaping a husband she believed to be a murderer; and Flora Bigelow Dodge, a vivacious woman determined, against all odds, to obtain a "dignified" divorce.
