What an utterly chilling story. The idea that Frank is Neville and that Neville goes to see his self that has gone back in time and been tortured is so chilling and creepy. That is so scary to know whats going to happen to you... would he prevent it? Apparently not.
You did a really good job of getting inside his head and his thoughts. It's just like Neville to be the one to find the timeturner and go back, except, this time, he gets into a serious muddle, that was supposed to happen in the first place.
My only complaint is that Augusta... wouldn't she know that her 'son' didn't just appear out of nowhere? Dumbledore would have to tell her what really happened, but in canon, Neville's grandmother is always telling Neville he's not living up to his father, and what a bad wizard he is, and she was scared that he was a squib. But knowing the events of the future that lead to the past... wouldn't she have reason not to be scared? Just bringing up some ideas.
I really also liked the way you made the character ambiguous. I thought it was Ginny, first, and then found out that it was Neville, and you slowly unveiled that to me. You gave the readers tiny hints and then tied it all together. I liked also how Dumbledore didn't want to know the future. It shows what a great wizard he is, that he doesn't find need to prevent any mistakes or death. It also shows that what happens needs to happen, and that it is not wise to muddle with time.
I also liked the repetition of the last 'blurb' in the beginning and end. In the beginning, it kind of works for Frank, because it's so insane--"I hear them whisper. I don't belong." But then in the end, it works for Neville, after you've learnt what happened. He doesn't belong there.
You just did an amazing job on this story. Once again, it was so chilling and creepy, but so good. You slowly unveiled it and kept the anticipation level at a high. It was very twisted to think that he's Frank and he kind of has to be to ensure the future... but that's just... weird. This was such a good idea, and I'm so glad I got to read it. You have so much potential as an author, and I hope you keep writing.
Author's Response: Well firstly... I thought about the whole Augusta thing myself, but maybe that is why she is so hard on him... that was my thought. She knows how he is supposed to turn out, and what it will mean if he doesn't, that is why she is worried, she doesn't see Frank in the insecure boy that Neville is... Do you see what I mean?? ---- Thank you for the great review, I am really glad you liked it! Oh, I will keep writing, no worries, and thank you for thinking me a good one at that!
