You're very repetitive, and at times there seems to be a lack of continuity. It can be somewhat off putting.

I started reading this fanfic yesterday because the premise sounded inventive and original. I was not disappointed, the changes to canon were interesting and innovative. I really enjoyed reading Slytherin Harry, unfortunately I have a few points I'm confused on and would like to elaborate on here. I hope you won't take this the wrong way, as you seem like a great writer and all, I just am confused.

First of all, why is Harry acting like a Gryffindor? He's in Slytherin, why would he care about Ginny or any of the Gryffindors when they've done nothing but be mean to him and mistreat him? This part makes no sense. If he's in Slytherin, why do all the Slytherins dislike him? Because he's going against their ways. If he has Voldemort's soul inside him, he really should be more cold and arrogant.

I also am quite baffled by how no one notices Harry's eyes turning red/and or Voldemort being back, and his sudden strong abilities. Why is no one noticing this stuff? Also, Snape should not hate Harry, he should be respecting him, he is under his house, after all, and not a Gryffindor like his father.

I am glad that for once, Dumbles is not the villain and seems to be kind, if not manipulative. I'm so sick of writing Evil Dumbledore and seeing it, it's nice to see one with the man like a human being. Also, the inconsistencies in the plot baffle me. Like, one second, Harry is helping Ginny, being nice to her, the next he breaks her heart and is mean to her? What the heck, that part baffled me. I'm not sure what to make of some of these plot changes.

Your grammar and spelling is amazing, there's nary any flaw in it. Judging by the update date (it's been nearly three years) you're probably never going to update this story again, but it doesn't hurt to go back over your work and edit it. I've been reading a book that's published, and while the premise is good, the spelling errors in it are RIDICULOUS. It's a published work, not a fanfic. I've seen fanfiction with better writing than published work. You have to wonder sometimes.

Anyhow, back to the story. It seems to me that Sirius is also a bit out of character. Would he really not accept Harry based on him being in a different house? It's nice to not see Harry always being friends with the Weasleys; many authors use the same cliched Slytherin Harry concept. Yours is fairly interesting and I look forward to reading more of the chapters.

Finally, I want to ask: I'm not saying I want Harry to be completely like a Gryffindor or a Slytherin, I just want him to be somewhat consistent with how the plot defines him. I'm glad he's not as idiotic as the book makes him out to be, the book Harry is very dull, in my opinion. I love intelligent Harry, so I'm glad he's still very smart. Also, that twist with the goblins? Ingenious. I'm so TIRED of goblins instantly respecting Harry Potter for no real reason. It bores me.

That twist with Marge? Awesome. I've only seen one fanfic that humanizes her. She's not very likable. And Gilderoy, well, no one will miss that pompous scumbag. Overall, I really like this fanfic, but I do wish I could see more of the Slytherin side of Harry. In other words, I prefer him to have more of a cynical/antihero feel to him.

Do please continue writing this someday, if you ever get the chance.

This fic is bloomin' AWESOME!

But PLEASE don't kill Sirius off too! Losing Remus was bad enough, not to mention Snape being insane...
Although, Snape being a total bastard despite Harry being a Slytherin seems to fit FAR better than if he'd be nice.

You overpowered the diary

excellent story. why was it canceled

And so it ends. I liked the story, well enough. You avoided many cliches. He was not powerful enough to claim the signet, he had memories of the future but couldn't remeber most of them, he was a Slytherin but retained Gryffindor traits, he was in Slytherin but wans't the Slytherin year-leader.
