Clarke's Universe — Arthur C. Clarke

In A Fall of Moondust, time is running out for the passengers and crew of the tourist-cruiser Selene, incarcerated in a sea of choking lunar dust. On the surface, her rescuers find their resources stretched to the limit by the pitiless and unpredictable conditions of a totally alien environment. The Lion of Comarre presents the far-flung future where one city of extraordinary means was built on Earth -- Comarre -- and it is rumored to still exist. None but a few know of its location. A young man with great prospects and no worries goes on a hunt for the fabled city, and what he finds is something mankind has only dreamed of.
