Wonderful tribute to Alan Turing's great accomplishments, while also acknowledging his horribly unjust treatment by the British government at that time. I love that children can discover his story in this way. It's not a exactly a story with a happy ending, and the author doesn't shy away from the ugly truths Alan Turing had to confront, but does so in a way that is appropriate for young readers. The illustrations are beautiful, with a lot of small details and a colorful elegance that fits the setting of the story and is perfect to draw the attention of its young audience too.
