Zola and Captain Thorne are on the run, and together with Scarlet and the Wolf they plot to overthrow Queen Levana. The fugitives place their hopes on Cress—imprisoned on her satellite companion since childhood among nothing but net-screens. The time Cress spent enslaved by the Queen of the Moon made her an excellent hacker—unfortunately, she just received an order from Levana to track down Zola and her accomplice. During a daring attempt to rescue her, everything goes not quite as planned. Cress finally gets her freedom, but at a dear price.
Meanwhile, Queen Levana prepares to marry Emperor Kai, and she won’t let anything or anyone interfere with that.
Cress, Scarlet, and Zola never signed up to save the world—but perhaps, besides them, no one else can.
