In the eighteenth glorious year of Enclosure, long after The Flood, a young girl named Honour moves with her parents to Island 365 in the Tranquil Sea. Life on the tropical island is peaceful - there is no sadness and no visible violence in this world. Earth Mother and her Corporation have created New Weather. Sky colour is regulated and it almost never rains. Every family fits into its rightful, orderly, and predictable place...Except Honour's. Her family does not follow the rules. They ignore curfew, sing songs, and do not pray to Earth Mother. Honour doesn't fit in with the other children at the Old Colony School. Then she meets Helix, a boy who slowly helps her uncover a terrible secret about the Island: sooner or later, those who do not fit disappear, and they don't ever come back.
