"Miller introduces readers to a progressive American female figure, known by many as 'Red Kate', and allows the audience to better understand O'Hare's contributions to the Socialist Party during its heyday in the first two decades of the twentieth century. The dedication and admiration that the author feels for her subject is clearly revealed; however, objectivity is not compromised. While presenting O'hare's agenda, Miller also analyzes some of the activist's seemingly inconsistent views-namely her attitudes toward blacks, and sometimes even women. A valuable bibliographic essay takes interested readers on a brief odyssey of the author's research. She points to avenues for additional information on may of the people, places, and ideas key to this biography."--Missouri Historical Review
