The Ruins of Langeles are up for grabs, and two walking cities stand on the brink of war.

Saud has arrived, Runner 17 is near death, the women of Nowhere are missing, and Roderick's plot to destroy Manhatsten is underway. Never before has Manhatsten faced such danger. Enemies lurk both inside and outside the city, and there is an assassin in Daniels's ranks.

It will take all the power of the sisters of the Order of the Eye to protect the city. But Alexa Turon has seen the future, and she knows what's coming, she knows if they don't do something, the city will fall. Can she and her new allies change the future or is too late to stop the inevitable?
