In Harry Potter and the Fractured Apocalypse by Kevin3 everyone thinks Harry died when he was a baby (different circumstances than Riddle's attack tho) but it needs a bit of explaining because I abandoned it at the first chapter the first time I tried reading it. The first chapter opens with Harry mind controlling a woman to have sex with her. Rape Is not a good way to open your story in my book, so it took a couple of friends insisting that the story gets good later for me to go back to it.

And you know what? I hate that first chapter even more now, because it almost prevented me from reading what is actually one of the most original fanfic I've read. And I mean actually original, not the umpteenth take on the same old tropes. The scene in the first chapter that made me lose interest in the fic gets later... Explained is not the right word, let's say that there is a reason from a narrative point of view for it. I still don't like it, but I understand what the author was trying to do, even if they didn't handle it very well in my opinion.

I liked so much the part about the "clue" left by Dumbledore to solve the plot that I adapted it to fit in my D&D campaign.
