I’m slowly realizing that it’s the little things that add up when writing. So much of my writing is intuitive that I don’t always understand what I’ve done until I go back and read the book. Take, for instance, my heroine’s perfume in THEORY OF MAGIC. I usually give my characters scents, and normally they’re just convenient additions to the sensory build-up of love scenes.
But in this case, I have a blind hero. So the heroine’s scent becomes a very important part of the book layering. If she’s not wearing it, he can’t know where she is unless he hears her voice or recognizes her footsteps. So he needs to notice if she’s not wearing it and wonder why.
