I am making a graphic novel of the scenes where Tally is traveling to the Smoke. Uglies - Scott Westerfeld
In the book Uglies by Scott Westerfeld, the main character (Tally) has to find her best friend that left the city for a city called the Smoke. The Smoke is a place for people that don't want to become a pretty. She left Tally a riddle to help her find her way to the Smoke.
