James S.A. Corey is the writer of The Expanse trilogy of sci-fi books, beginning with Leviathan Wakes, continue with Caliban's War (my personal favorite of the trilogy), and ending with the recent Abaddon’s Gate.
Reading is one of my favorite and most consistent sources of inspiration for my games. My favorite books fuel many of my mechanics and settings, but also, generally get me excited for a premise and theme.
I can't help myself. I'm on a massive space binge lately. I changed Dawn Sector from faux-Napoleonic to sci-fi to broaden its appeal and give myself more flexibility on the design (plus I like sci-fi), but it wasn't my intent to return to this theme again.
