Final week of a dystopian hoax tale

A plane drops an atomic bomb, after which the pilot is ordered into hiding by the command centre. They have even rented a piece of jungle for him, where he starts a micro-community. However, a power struggle ensues between his half-blind granddaughter Ruby, the insomniac bodyguard, the priest appointed as her guardian by the pilot, and a policeman who says he is family. Things explode when Ruby befriends a mysterious stranger.
