The ship / Antonia Honeywell.

""Powerful, haunting, and beautiful," (M. R. Carey, author of The Girl With All the Gifts) The Ship is a luminous and genre-defying debut novel that follows a young woman's coming of age in a world where she has no future. 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. 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; and no-one can tell her where they are going"-- Provided by publisher.
