Thank you for all your votes! I tallied up the votes both here and on Facebook and this image is the clear winner with 34 votes. Second place was the little boy peering over the woman’s shoulder (24), which I have to admit fits the book very well, but one reader mentioned that the little boy gave her “the creeps” and that sort of wrecked the image for me. Third place was the woman carrying the suitcase (17). I liked them all, so I’m going with your choice, which I think really captures Kim and Cody (aka Susanna and Tyler) and the water setting of Annapolis, Maryland. The original image has no color in the sky and water, so I added it. I’ll do a neater job of it in the finished product, but I actually like that the picture has a “painterly” quality to it, since that fits the story of a mural artist.
The cover image that received the fewest votes (2) was this one on the lower left, which I actually like because the story is very much about Kim and the secrets of her computer, but clearly it didn’t grab anyone other than me!
Thanks again for your help. I’ll be prettying up the cover image a bit, adding my name and the title, and as soon as I finish editing the very messy scan of the book, it will be ready to upload as an ebook.
