Which Cover Looks Best

The next to last. Regardless of the story the cover itself is intriguing enough for me to be curious. That's the one. 2 is a close one bc of the Noir classic look

What’s the book about?

The last one isn't good because it's obviously AI and there's no obvious connection between a gold high heel and someone freezing to death in the snow. The first two aren't bad, but I doubt if they convey the feeling of the book. So, 3 is probably the best. Hill was a romance writer, and this one evokes a sense of romance, but avoids being obviously AI generated.
