I like details. Little things tell me everything about people, their society, their hopes and fears, the sky above them, the rock beneath them.
When I began writing Luna, I knew I would be building a world from scratch, but also one that adhered to the constraints of the physical realities of the moon. The Moon may have been Heinlein’s Harsh Mistress but we’ve learned a lot about Lady Luna since and she’s got leaner and meaner. A lot meaner. I wanted those facts to shape the world and lives of my characters, from low gravity to moon dust, which is seriously nasty stuff. I suppose it’s a “hard science fiction” book—though that’s an expression I hate. Hard science technically shapes the lives, loves, jealousies and ambitions of every one of my moon’s one point seven million citizens.
