"Terra Incognita": D. H. Lawrence at the Frontiers consists of nine essays by scholars from five countries. They show how Lawrence explored the "terra incognita" not only of geography but also of consciousness and human relations. The 1920s emerge as a watershed in his work. These essays present the first criticism to utilize new texts and research in the final prose volumes of the Cambridge Lawrence Edition. This includes all the essays Lawrence wrote in America about Southwestern and Mexican Indians (Mornings in Mexico and Other Essays, 2009). Authors are Michael Hollington, Paul Poplawski, Judith Ruderman, Edina Pereira Crunfli, Jack Stewart, Keith Cushman, Tina Ferris, Julianne Newmark, and Hyde. Color illustrations are by Lawrence, Georgia O'Keeffe, and Dorothy Brett. The book will interest both general readers and scholars of Lawrence and twentieth-century literature.
