With it there is continuity of character. Please look at the second possible cover and read the tag-line of the cover.
This one speaks more to the content in the book. Since Macy is still the main character, I don't know that she needs to be on the cover again. It does tell you this is a Macy McVannel novel.
I will be finishing all edits and making a decision by the end of the week. I have an informal poll going on my author page on Facebook. So far cover two is ahead 7-2. I will be interested to see what tomorrow brings. Feel free to comment with feedback. I am open to what you think.
