By definition it uses and plays and delights in time. It delights in the interlacing of chronologies and the consequences of that interlacing. And those have personal and psychological expressions in a character. Aside from other issues of writing, psychological characterization is what narrative can do best.
Yeah, and the language the "we" has, and the character the "we" has. Because that was the part of the book that I didn't plan out, but the part that I was most curious about as I was writing. You know what you're doing, but you're sometimes still sort of curious as you're writing it.
It's not that I wrote those details, but photos can give you the confidence that you have a real feel for the landscape. Then you can invent with a solid kind of faith, and recreate a feel and flavor of the time, and, one hopes, a tonality, a sense of that time having been lived by those characters.
Like most people, Im fascinated by characters who are completely flawed personalities, riven by anguish and doubt, and are psychologically suspect.
