Downsiders

Beneath the sewer grates and manholes of the city lies a strange and secret world called the Downside. Every Downsider knows that it's forbidden to go Topside, and most fear a collision of the two worlds. But fourteen-year-old Talon is curious about what goes on above ground, and one day he ventures out in search of medicine for his ailing sister. There he meets Lindsay, who is as curious about Talon's world as he is about hers.
