Winner of the inaugural Chicken House/London Times Children's Fiction Competition, which called it "a funny, clever, towering adventure."Because of climate change, much of 23rd-century England is underwater. Poor Lilly is out fishing with her trusty first mate, Cat, when greedy raiders pillage the town—and kidnap the Prime Minister's daughter. Her village blamed, Lilly decides to find the girl. Off she sails, in secret. And with a ransom: a mysterious talking jewel. Along the way she forms a wary friendship with Zeph, a punky raider boy. "If I save the Prime Minister's daughter," Lilly reasons, "he's sure to reward me." Little does Lilly know that it will take more than grit to outwit the tricky, treacherous piratical tribes!
