Plot details

The moon is colonised, and has as one of its attractions a "cruise" across one the craters filled with dust. The specially designed "boat" skims over the sea of dust that is so fine it behaves almost like water.

On this cruise though, there is a problem, when a small moon-quake causes an underground cavern to collapse, upsetting the equilibrium, and causing the boat to capsize and sink in the dust.

With limited air supply and no one quite sure where they are, how will they get rescued? How will the occupants pass the time without climbing the walls?
