I've gotten some great comments in reviews about my characters, so I thought I'd talk about that for a bit.
A few years back my critique partner sent me a quote about how characters aren't furniture. It was her gentle way of pointing out that I had a character in my current work in progress that just served the plot by showing the main characters from place to place. The quote made me think and that character ended up with a personality and a story arc of his own, despite the limited screen time I'd planned for him.
Ever since then when I approach a supporting character, I like to imagine what the story would be like from their point of view. While the main characters are taking up much of the action, I picture the extras living their own lives. If challenged, I'd want to be able to go and write their story.
The great thing about working with novels is that you get the chance to develop these secondary characters. In Angel 1089, I was able to give readers a good view of Ronnie and Mattie, Hank and Ian. (And yes, I am in fact working on Hank and Ian's story, so this philosophy works.)
I didn't get the chance to really flesh out the supporting cast in Beyond Meridian. In novellas, you really have to keep the focus on the main couple and main story arc. I'm working on one right now, and the challenge is to keep the secondary characters from being more than furniture, despite the limited word count.
Good thing I'm always up for a challenge.
