Frey and Rafi are inseparable . . . but very few people have ever seen them together. This is because Frey is Rafi’s double, raised in the shadows of their rich father’s fortress. While Rafi has been taught to charm, Frey has been taught to kill. Frey only exists to protect her sister. There is no other part of her life. Frey has never been out in the world on her own – until her father sends her in Rafi’s place to act as collateral for a dangerous deal. Everyone thinks she’s her sister – but Col, the son of a rival leader, is starting to get close enough to tell the difference. As the stakes grow higher and higher, Frey must decide whether she can trust him – or anyone in her life.

Frey's sister Rafi—no longer a twin in features, but still a twin by birth—is the wild card. Are the sisters on the same side . . . or are they playing to their own agendas? If their father is deposed from Shreve, who will take control? And what other forces may be waiting in the wings?

IT'S TIME TO COME OUT OF HIDING 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. With Youngbloods, master storyteller Scott Westerfeld decisively brings back his most iconic character and merges his Impostors and Uglies series into a breathtaking tale of rivalry, rebellion, and repercussion.
