The book starts with diagrams and the breakdown of clairvoyant powers, but trust me you can skip this. Samantha Shannon incorporates the complex history of an alternate reality seamlessly into the story, giving it a rare sense of authenticity. What if a past King of England dabbled in the dark arts? We’d find ourselves in a world where clairvoyants are hunted down and feared. It all comes down to one girl with a rarer power to save more than one race of people.
