The Walled City
by Ryan Graudin
Jin, Mei Yee, and Dai all live in the Walled City, a lawless labyrinth run by crime lords and overrun by street gangs. Teens there traffic drugs or work in brothels - or, like Jin, hide under the radar. But when Dai offers Jin a chance to find her lost sister, Mei Yee, she begins a breathtaking race against the clock to escape the Walled City itself.
