During the height of the Blitz in London, the air raid rescue squad operating out of Mrs. Lucy’s house is close-knit and ever-watchful. When a new volunteer named Jack shows up, his odd behavior—not eating, disappearing during the day for a mysterious job—isn’t concerning at first. The sleepless stress of the job is hard on everyone. Soon, Jack is in high demand, due to an almost uncanny talent for finding buried people still alive under the rubble… But how does he do it? As the narrator, another member of the squad also named Jack, begins to investigate, the truth turns out to have a dark, tragic twist. New York Times bestselling, multiple-award-winning author Connie Willis’s surprising and deftly rendered classic 1991 novella “Jack,” a finalist for the Nebula and the Hugo awards, is a must-have for readers of her beloved works set in World War II, including “Fire Watch,” Blackout, and All Clear.
