It happened to me yesterday. So I took a break and worked on a few new characters that will appear in my third novel. So far, my favourite is Dr. Simon Bishop who appears in chapter three:
"No one ever forgot Dr. Simon Bishop. Once you laid eyes on him he became a benchmark in your future assessments of how truly bizarre other people you met looked—or came across. Because it wasn’t just how he looked. There was far more to Simon Bishop’s bizarre factor than his physical features though one had to admit his head was quite alarming."
So, I've posted two photos below that might inspire you.
Personally, I love the photograph of the woman in blue - she could definitely inspire a saga!!
