Ask most bookworms to name the best Vietnamese novel and you'll get answers ranging from 2016's "The Sympathizer," by Vietnamese-American Viet Thanh Nguyen, to 1990's "The Sorrow of War," by Bao Ninh.
Which makes Nguyen Phan Que Mai's "The Mountains Sing," the first major novel penned in English by a Vietnamese writer, a breakout moment for Southeast Asia's fastest-growing economy.
