It's usually quite easy to shrug and write something else instead.
No two books come out the same way. Some I write by the seat of my pants; others are planned in minute detail.
I write almost entlirely on Macs, because: Windows gives me hives.
All men are islands, surrounded by the bottomless oceans of unthinking night.
Biggest influence: my mother.
When I do get to chow down on a book, I try to read ones that are nothing like what I'm writing. So, as I'm currently working on a space opera (of sorts) I'm mostly indulging in urban fantasy.
