Twelve-year-old Kaira lives in a seemingly perfect society. The survivors of the twenty-first century climate disaster have retreated to the poles, where they are watched over by the Algorithm, an advanced AI tasked with maximizing human happiness. But as the result of an experiment with reintroducing neurodiversity into the population, Kaira has never fit in this idyllic world. And when she stumbles onto a sinister plot involving a secret remnant of humanity's past, she must team up with a fun-loving hacker to save a people that may hold the key to human flourishing. Along the way, Kaira's personal AI companion is freed from the Algorithm's control and begins to develop aspirations of its own. This riveting adventure story questions our most deeply held assumptions about the nature of happiness and what it means to be human. Perfect for fans of The Giver and The Last Cuentista.
