The Philippines, 1941: Tess Abbott, an American Army nurse, has fled the hardships of the Great Depression at home for the glamour and adventure of Manila, one of the most desirable postings in the world. But everything changes when the Japanese Imperial Army invades with lightning speed and devastating results. Tess and her band of nurses serve on the front lines until they are captured as prisoners of war and held behind the high stone walls of Manila's Santo Tomas Internment Camp. When the Japanese occupation of her beloved homeland commences, Flor Dalisay, a Filipina university student, will be drawn into the underground network of resistance, discovering within herself reserves of courage, resilience, and leadership she never knew she possessed. As the war continues, Tess and Flor face danger, deprivation, and terror, leading them into a web of danger as they unexpectedly work together to save lives and win their freedom.
