It's 1967, and Kitty Granger is about to accidentally become a spy. A working-class girl from London's East End who today would be recognized as autistic, she's spent sixteen years hiding her peculiarities from the world. But after her hyper-awareness helps her survive a chance encounter with a Russian spy ring, two British secret agents offer her a job. Kitty's first mission draws her into a fascist conspiracy led by a prominent politician--who's also an unreformed Nazi sympathizer. With help from her team, Kitty must use her wits, training, and instincts to get out alive. And she might as well save the country while she's at it.
