My solution gives the reader hope that the hero and heroine can have the HEA that is so craved in romance, yet also gave me an opportunity for a sequel, which I am working on now. Sarah's Passion will be a continuation of the story. Rather than assume one is coming, some readers would rather divulge the entire plot on a VERY public site, and not just spoil the ending, but discourage others from purchasing the book and drawing their own conclusion, and being able to look forward to reading more about Sarah and Wolf. The lack of understanding exhibited by some is defeating at times, but giving in would let them win, and I won't do that. I'm a good author, and I know it.
