The spies of Shilling Lane : a novel / Jennifer Ryan.

Mrs. Braithwaite, self-appointed queen of her English village, finds herself dethroned, despised, and dismissed following her husband's selfish divorce petition. Never deterred, the threat of a family secret being revealed sets her hot-foot to London to find the only person she has left--her clever daughter Betty, who took work there at the first rumbles of war. But when she arrives, Betty's landlord, the timid Mr. Norris, informs her that Betty hasn't been home in days--with the chaos of the bombs, there's no telling what might have befallen her. Aghast, Mrs. Braithwaite sets her bullish determination to the task of finding her only daughter. Storming into the London Blitz, Mrs. Braithwaite drags the reluctant Mr. Norris along as an unwitting sidekick as they piece together Betty's unexpectedly chaotic life. As she is thrown into the midst of danger and death, Mrs. Braithwaite is forced to rethink her old-fashioned notions of status, class, and reputation, and to reconsider the question that's been puzzling her since her world overturned: How do you measure the success of your life?
