The ship
(Book)

"London burned for three weeks. And then it got worse ... Lalla has grown up sheltered from the chaos amid the ruins of civilization. But things are getting more dangerous outside. People are killing each other for husks of bread, and the police are detaining anyone without an identification card. On her sixteenth birthday, Lalla's father decides it's time to use their escape route--a ship he's built that is only big enough to save five hundred people. The ship is a haven, bountiful and safe from the destruction and disease that plague the rest of civilization... But the utopia her father has created isn't everything it appears. There's more food than anyone can eat, but nothing grows; more clothes than anyone can wear, but no way to mend them; more screens than anyone can use, but no way to connect them to the outside world; and no one can tell her where they are going and she aims to find out why"--,Provided by publisher.
