Oxford Street burned for three weeks. The British Museum is squatted by ragtag survivors. The Regent's Park camps have been bombed. The Nazareth Act has come into force. If you can't produce your identity card, you will be shot.
Lalla, 16, has grown up sheltered from the new reality by her visionary father, Michael Paul. But now the chaos has reached their doorstep. Michael has promised Lalla and her mother that they will escape. Escape is a ship big enough to save 500 people.
But only the worthy will be chosen.
Once on board, as day follows identical day, Lalla's unease grows. Where are they going? What does her father really want?
