Ah. Lots and lots of stories set on the moon - Varley in particular has many in the Eight worlds series - but most of them seem to be short stories, like Heinlein's The menace from Earth or Varley's The Phantom of Kansas. I suspect this is at least partly due to the short story being the solid foundation of SF during my formative years, magazines being the main technique for diffusion. Ans after an American had set boot on the regolith, a large part of the magic evaporated.
So, another Bova - Millennium - plus Assenblers of infinity (Kevin Anderson and Doug Beason), both of which spend the majority of their time on the Moon, even if some is taken on Earth or in orbit, and Niven's The Patchwork Girl, even if neither the principal character (Gil Hamilton) not the title one are loonies, the action is all on our major satellite.
