Marian Sutro is an ordinary nineteen-year-old living in extraordinary times. She comes of age in England during World War II (yes, another one, but I promise this is good!), and she cannot escape the desire to serve her country. She is accepted into a secretive program, spirited away to a training camp in the wilds of Scotland, and then parachuted into occupied France, where she must work undercover. She does not entirely understand her position, but the stakes could not be any clearer. Despite the over-the-top storyline, this is a quiet book that does not flaunt any James Bond tropes, and that is what makes it so piercing and believable.
