In a timely and radically new reappraisal of George Orwell's fiction, Loraine Saunders reads Orwell's novels as tales of successful emancipation rather than as chronicles of failure. Contending that Orwell's novels have been undervalued as works of art, she offers extensive textual analysis to reveal an author who is in far more control of his prose than has been appreciated. Persuasively demonstrating that Orwell's novels of the 1930s such as A Clergyman's Daughter and Keep the Aspidistra Flying are no less important as literature than Animal Farm and Nineteen Eighty-Four, Saunders argues they have been victims of a critical tradition whose practitioners have misunderstood Orwell's narrative style, failed to appreciate Orwell's political stance, and were predisposed to find little merit in Orwell's novels. Saunders devotes significant attention to George Gissing's influence on Orwell, particularly with regard to his representations of women. She also examines Orwell's socialism in the context of the political climate of the 1930s, finding that Orwell, in his successful negotiation of the fine balance between art and propaganda, had much more in common with Charlie Chaplin than with writers like Stephen Spender or W. H. Auden. As a result of Saunders's detailed and accessible analysis, which illuminates how Orwell harmonized allegory with documentary, polyphonic voice with monophonic, and elegy with comedy, Orwell's contributions to the genre of political fiction are finally recognized.

Albert Shanker (1928-1997) lived the lives of several men bound into one. In his early years, he helped to found modern teacher unionism. During the 1980s, as head of the American Federation of Teachers, he became the nation's leading education reformer. Shanker supported initiatives for high education standards and accountability, teacher-led charter schools, and a system of "peer review" to weed out inadequate teachers. He also fought for "tough liberalism," an ideology favoring public education and trade unions but also colorblind policies and a robust anticommunism?all of which, Shanker believed, were vital to a commitment to democracy. Richard D. Kahlenberg is the first to offer a complete narrative of one of the most important voices in public education and American politics in the last half century.

The famed fighting force of Union General William T. Sherman was plagued by a lack of first-rate cavalry--mostly because of Sherman's belief, after some bad experiences, that the cavalry was largely a waste of good horses. The man Grant sent to change Sherman's mind was James Harrison Wilson, a bright, ambitious, and outspoken young officer with a penchant for organization. Wilson proved the perfect man for the job, transforming a collection of independent regiments and brigades into a fiercely effective mounted unit. Wilson's Cavalry, as it came to be known, played a major role in thwarting Confederate General Hood's 1864 invasion of Tennessee, then moved south for the celebrated capture of Selma, Montgomery, and Columbus. Despite such success, it is this book that is the first overall history of the Cavalry Corps. In addition to meticulous description of military actions, the book affords particular attention to Wilson's outstanding achievement in creating an infrastructure for his corps, even as he covered the Federal flanks in the withdrawal to Franklin and Nashville.
