The world is flooded by a sea of toxic snow humans are unable to swim in. All around the world are large canopy trees that reach from the bottom of the sea to the very top right into space. You have lived in the top of a canopy tree your whole life, using it for drinking water and hunting bugs on the frozen top (a layer connecting the tops of the canopy trees to each other). Unfortunately, water is running dry and you must find a new way to survive.
