Have you ever read stories where animals play a major role in the story? Dogs, cats, and horses especially. People love animals and that pours over into not only reading choices, but writing choices for authors. I, for one, fit that bill.
Have you ever broken up with another person, then ran across them down the road? Did you wonder why it hadn’t worked? Wish for a second chance? Did you or someone you know ever take that leap of faith and give the relationship one more try? Was the second time the charm or was the experience only a matter of same issues, different day?
