This is the tale of a irrepressible friendship between two women doing very unusual jobs. It is World War II and England is barely holding its own as the Germans begin bombing runs over Britain. Maddie, one of the two women, is a mechanical wizard who earns herself a place in the skies as a highly skilled pilot. Queenie, the other, is a spy. Consider how many female spies and pilots you can picture from that era and you have the underpinnings for a lot of suspense with a new twist. I can’t give away more of the plot without being a spoiler. Ignore the book’s cover and be aware the book is written for Young Adults, but enjoy it.
