Code name Verity

I'm obsessed with this book. I love historical espionage and generally hate young adult fiction, so I was afraid my beloved genre was going to be perverted by love triangles and simplistic, linear narratives. But that was certainly not the case. The characters are complex (sometimes heart-breakingly so)and the story is intricate and historically accurate. I can completely see Virginia Hall and Christina Granville living in the same universe as the characters in the book
