Floodland: Marcus Sedgwick

Zoe, left behind in the confusion when her parents escaped, survives there as best she can. Alone and desperate among marauding gangs, she manages to dig a derelict boat out of the mud and gets away to Eels Island. But Eels Island, whose raggle-taggle inhabitants are dominated by the strange boy Dooby, is full of danger too.

The belief that she will one day find her parents spurs Zoe on to a dramatic escape in a story of courage and determination that leads to an unexpected and touching conclusion. Floodland has a powerful and emotive theme, handled with warmth and humanity.
