There are some plot details, too, that don't add up. But, in the end, Code Name Verity is a competent book that I would have enjoyed much more at age 14 than as an adult. It's very young-adult, in everything from pacing to plot elements to the characters' voices, and I wonder why Wein chose that route, given that the protagonists are women in their 20s whose stories would suit an adult book just fine (despite that, they're rather jarringly referred to as "girls" throughout, perhaps to make them seem closer to the intended audience's age).
Overall, Code Name Verity is an enjoyable book. The story is gripping, with tension and danger throughout--naturally enough, as one of the protagonists spends the book as a Nazi prisoner. The characters are fairly vivid, and I enjoyed reading about a pair of tough, capable women. I was unaware of the role of women pilots in England's Air Transport Auxiliary during the war, and so especially enjoyed reading about Maddie's advancement as a pilot. The author, a pilot herself, does a great job of communicating her love of flight, and her clear knowledge of planes adds verisimilitude. Wartime England and occupied France are both brought to life, and the writing style is adequate without drawing attention to itself.
“Code Name Verity” is unlike any book I’ve ever read before. A good book is one I enjoy as I’m reading it. A great book is one that will stick with me and, in ways, haunt me. This is a great book. A-
