First, if a cover has a picture of the characters, that's how I tend to imagine them. So, with that said, I struggled with my depiction of the characters. The Amazon ebook is of a white woman with straight brown hair. In the book she's described as having coppery curls. I also thought she might be black.
Though it was not directly stated, I kind of assumed the characters(at least the hero and his cousin) to be dark skinned Jamaicans. So, I'm picturing them this way, and the another format shows the hero being white. It was just a little too much character confusion.
I don't care what ethnicity the characters are, but I do like the character descriptions to be a little more detailed and forthcoming.
It seems petty, but it was very distracting.
