Fourteen-year-old Charlie Matters is up to no good, but for a very good reason. Without parents, peerage, or merit, ducking school but barred from actual work, he steals what he needs, living day-to-day until he’s old enough to enlist to fight the Germans. After barely surviving the Blitz, Charlie knows there’s no telling when a falling bomb might end his life. Fifteen-year-old Molly Wakefield has just returned to a nearly unrecognizable London. One of millions of people to have been evacuated to the countryside via “Operation Pied Piper,” Molly has been away from her parents—from her home—for nearly five years. Her return, however, is not the homecoming she’d hoped for as she’s confronted by a devastating reality: both her parents are gone. Without guardians and stability, Charlie and Molly find an unexpected ally and protector in Ignatius Oliver, and solace at his book shop, The Book Keep, where A book a day keeps the bombs away. Mourning the recent loss of his wife, Ignatius forms a kinship with both children, and in each other—over the course of the greatest armed conflict the world had ever seen—they rediscover the spirit of family each has lost.
