Not My First Choice
The character Indiana was not the main character for 'Fall to Earth'. As written previously, I conceived of this story as a tv series (not that I'm a tv writer, but the episodic format appeals to me) and the foil for the viewer was one of Arthur's sisters [slated for a later sequel].
After the hard drive crash, I continued to work the idea, but not pushing the story forward. When I wrote again in 2008, I had to rethink the idea as a novel. As my wife will point out, I have at least one copy paper box full of abandoned handwritten stories from all the way back to my high school days, so a novel wasn't a foreign idea, nor unappealing.
I was enamored with the idea of the main character of a mythology tale not be the protagonist. So, Indiana came about as someone who was necessary for the plot, the mythos and with whom I could reimagine the one side (or point) of one of the most famous love triangles known - Lancelot, Arthur, and Guinevere.
Indiana evolved, grew, and crystallized with the process of writing and editing her story. She certainly wasn't my first choice, but she's really the best choice. She'd say so, too.
