The world never ended in fire and ice. The people were consumed by it and now control the elements. The Fires have harnessed the power down to an art while the Waters cower in fear of their abilities, remaining weak and hopeless. Seventeen-year-old Sage Sinclair hopes to dispel the weakness of her Water people because she knows that if she doesn’t do anything, no one will. When she discovers something special about herself, she seeks Humble Narcissist Ruler Agni in the great fire city, Saint Firefly. Once she gains his seal of approval, she’s admitted into Erra Academy where she secretly sparks a revolution among her ennui peers—a revolution to fight back against the Fires. She has every hope in her movement, just as long as her feelings for a handsome and frivolous Saffron Larkspur don’t get in the way—that, and Agni’s sudden fascination with her.
