"A twisting, sophisticated World War II novel following a spy who goes undercover as a part of MI5. But in chasing the secrets of others, how much will she lose of herself?"-- Provided by publisher.

Ambitious and clever, Evelyn Varley earned a scholarship to a prestigious academy well above her parents' means, gaining her a best friend from one of England's wealthiest families. In 1939, with an Oxford degree in hand and war looming, Evelyn finds herself recruited into an elite MI5 counterintelligence unit. Posing as a Nazi sympathizer, Evelyn must build a case to expose the treachery of a ruthless secret society seeking an alliance with Germany. Drawn deeper into layers of duplicity, those closest to her become embroiled in her investigation. In chasing the secrets of others, how much of herself will she lose? Her decision echoes for years after the war. -- adapted from jacket
