Publisher's Synopsis
12-year-old Petrel is an outcast, the lowest of the low on an ancient icebreaker that has been following the same course for 300 years. In that time, the ship's crew has forgotten its original purpose and broken into three warring tribes, the Cooks, the Officers and the Engineers. Everyone has a tribe except Petrel, whose parents committed such a terrible crime that they were thrown overboard, and their daughter ostracised. Petrel lives in the dark corners of the ship, trusting no one, speaking to no one except two large grey rats, Mister Smoke and Missus Slink. That is, until a boy is discovered, frozen on an iceberg, and brought onto the ship. No one knows where he has come from. Petrel hides him away in the forgotten corners of the ship, hoping he will be her friend. What she doesn't know is that for the last 300 years, the ship has been guarding a secret. A secret that could change the world.
