I just checked (20/11/2024) it is still up on Amazon. Sue the swine. A similar thing happened to me here on Amazon. I chose to follow a new writer and shortly afterwards started to read one of her stories, it was mine. I demanded she remove it and reported her to Medium. Sorted. On the one hand, I was pissed off, but then I thought it was at least a sign it was good. Plagiarism is some kind of flattery, I guess.
