Aiden and Minnie. Two of the least ordinary people you’re likely to meet. Aiden’s missing the first eight years of her life, yet she can play Beethoven’s Concerto without ever having been taught. Minnie can see people’s emotions, in vivid colour, no less. That doesn’t help much when she meets Aiden, who doesn’t seem to have any. When British Intelligence sweeps in, along with belligerent spies and a half-brother Aiden never knew existed, Minnie soon discovers that whatever Aiden might lack, she more than makes up for in intrigue. Getting to know one another will have to wait, though; when bullets start to fly, and the bodies begin to pile up, the two young women find themselves caught up in a clandestine war for control over the human psyche…and their own lives.
