Okay, I was looking through a list of some published books that started off as fanfiction on goodreads and I ran into this book called Indivisible and it looked super familiar. It took me a moment to realize why. I had seen nearly the exact same book cover on A. Meredith Walter's Find You in the Dark.
Find you in the Dark was published first and I don't want to actually accuse anyone of anything. I mean maybe they have permission, maybe there's enough variation. I mean they did add dog tags and a blonde head of hair in the background. Still, it bothers me quite a bit to tell the truth.
Can you normally pretty much just use someone else's cover? Can you hire the same models and use them in the same pose but oh I don't know put a purse around her arm and call it your original work? I wouldn't! At the very least it's unethical but with Indivisible already being on a fanfic list it sure makes me wonder :/
I mean are they different enough? Not to me they aren't but that's just my opinion.
Again, I don't know all the facts and maybe there's a legitimate good reason or someone has permission. :/
