Will Zyzo and Alixe manage to avoid it, while saving the members of their clan?

A poisoned cloud has spread across the earth.
Only a few teenagers were not exterminated by the cataclysm.
Alixe lives in the Louvre ("the Castle") with other privileged individuals, while Zyzo tries to survive by living in the Eiffel Tower ("the Tepee") with his clan. But when the animals are poisoned, food becomes scarce for those in the Tepee. For them, there is no doubt, the children of the Castle are guilty.
War is about to be declared!
