Another plagiarism incident. It seems pretty clear this one was no accident.
Sometimes text does get repeated unintentionally. One of my characters says, “You must trust me as I have trusted you.” I wrote this a couple of years ago. Wouldn’t you know it, I read The Tombs of Atuan, and that darn Le Guin woman wrote something almost exactly the same. I’m going to give her the benefit of the doubt and believe she wrote it by accident. Great minds, so on.
I considered changing the text in my story, but that character would say that in just those words. Fukafukafuka. For later worry.
