Here’s what I came up with. What do you think? I was leaning toward the red cover but when viewed as a thumbnail image [the size it will be shown in the Kindle store/Amazon page] the blue cover is much clearer. So, for now, the e-book version will use the blue. When print copies are available I may go with the red. I gotta say, if I saw that on the shelf [or better yet, right at the front of the store on display with the other best sellers!] I'd pick it up.
I’d love comments - after all, people really do judge books by their covers.
