Frey has spent her life in a family of deceivers, a stand-in for her sister, manipulated at her father's command. Free from them at last, she is finding her own voice--and using it to question everything her family stood for. Tally was once the most famous rebel in the world. But for over a decade, she's kept to the shadows, allowing her myth to grow even as she receded. Now she sees that the revolution she led has not created a stable world. Freedom, she observes, has a way of destroying things. As the world is propelled further into conflict and conspiracy, Frey and Tally join forces to put a check on the people in power, while still trying to understand their own power and where it belongs.
