Dushma lives with her aunt in several cavernous brick rooms hundreds of steps above the city.

People swarm around the base of the viaduct's pillars, perilously far below.

Dushma spends most of her time watching them, or walking the streets.

She isn't registered, so there isn't much else for her to do.can't go to school, can't use the underground, can't earn any money.

In fact, Dushma may as well not exist. Except, she does exist, and they've foundout-and now Dushma's on the run.

From whom, she does'nt know. Allshe knows is, she must find somewhere new to hide. And in the electrical labyrinth hundreds of feet under London's streets, a place where ordinarily, Dushma's not allowed to set foot, she thinks she's found the perfect place to disappear.
