Book excerpt: Caren Irr's survey of more than 125 novels outlines the dramatic resurgence of the American political novel in the twenty-first century. She explores the writings of Chris Abani, Susan Choi, Edwidge Danticat, Junot Díaz, Dave Eggers, Jeffrey Eugenides, Aleksandar Hemon, Hari Kunzru, Dinaw Mengestu, Norman Rush, Gary Shteyngart, and others as they rethink stories of migration, the Peace Corps, nationalism and neoliberalism, revolution, and the expatriate experience. Taken together, these innovations define a new literary form: the geopolitical novel. More cosmopolitan and socially critical than domestic realism, the geopolitical novel provides new ways of understanding crucial political concepts to meet the needs of a new century.
