I'm not sure which one is the U.S. cover. Basically it's the story of two women who get shot down over France - one is a special agent for England and the other is the pilot. It's about friendship. There are SS officers and torture and apparently it will cause a lot of crying, so it's not a light read, but there is humor and lightness in it. The reviews on Goodreads are pretty compelling. It also makes me curious about Wein's other work - anyone read her stuff?
