F. Scott Fitzgerald and Ernest Hemingway might have lived as contemporaries, but our understanding of their work often rests on simple differences. Hemingway wrestled with war, fraternity, and the violence of nature. Fitzgerald satirized money and class and the never-ending pursuit of a material tomorrow. In the capable hands of Scott Donaldson, however, the affinities between these authors become brilliantly clear, thus reorienting our understanding of twentieth-century American literature.
