Five towers. Five colors. One way out. Cipher risks everything to reach the Red Tower. He searches for the person who was once the most important in the world to him. He has left the friends who helped him discover himself. He has left a place where he had control, where his powers were the mind and the wind. Now Cipher must learn new powers to survive. He must channel his passions to thrive. And he must rise to the top of another tower before he can enter the Scouring again, where deeper secrets await.
