On this installment of ST, we speak with the New Mexico-based writer and biographer James McGrath Morris, who is the author of (among other books) the bestselling "Eye on the Struggle: Ethel Payne, The First Lady of the Black Press." Morris joins us to discuss his newest work, which is just out: "The Ambulance Drivers: Hemingway, Dos Passos, and a Friendship Made and Lost in War." As was noted of this historical biography by the New York Journal of Books: "[This book] delves head-first into the mercurial relationship of these two American literary legends.... Throughout this riveting biography Morris expertly narrates the journeys, relationships, and life-changing events that inspired two of the greatest authors of the 20th century.... A lively and engaging biography that takes a fresh look at the life of Dos Passos.... Although readers may at first hesitate to embark on yet another analysis of Ernest Hemingway, Morris' framing of the context of his fragile and contemptuous relationship with fellow literary giant John Dos Passos creates a worthwhile read. It will most certainly fascinate Dos Passos and Hemingway aficionados, as well as the casual literary biography enthusiast."
