In this incredibly moving and powerful story about climate change by one of France's greatest writers for children, the world is run by !ndustry and the only thing that matters is to buy, buy, buy. People live in crowded cities where cars are stacked vertically and shopping centres run miles into the sky.
On the day Celeste starts school on the 110th floor of a tower block, she meets a lonely, young boy.
The next day she doesn't return. Her blood has become as polluted as the seas and rivers. On a mission to save her, the boy battles the forces of !ndustry and takes her far, far away.
Will the world realise the truth of Celeste's disease? Will there be time for her, and the planet, to recover?
