In Julio Ortega's "Migrations," a Peruvian writer explores how immigrant speech and ethnic origins are a force of meaning that evolves beyond language. In "Hair," by Hilma Contreras, a Caribbean pharmacist is driven mad by a young woman's luxuriant tresses. These stories stretch from gritty reality to the fantastical in a mix that is moving, challenging, humorous, artful, sometimes political, and altogether spectacular.
