Wow, why haven't I seen this one before now, I wonder?! I must have been blind, because it's so good, much like some of the other fic's of yours, which I've read, that is!
Anyway, I love the start (very interesting), obviously, hehe, awesome plot and so is the character portrayal as well, as the interaction between them and the fic is very well written too!
So I wonder who this boy/young man is?! He's a Slytherin, yay, I love them, lol! Hermione's the only one that can see him and he's not dead, but neither a ghost, huh, wow, that sure is very intriguing, I say!
And he's been at Hogwarts for quite some time, I gather, he also seems to come from a wealthy/fine family (pure blood?!), I wonder who he is?!
When you mentioned Kreacher, Regulus and Sirius, then I first thought it might be someone along that particular line, but who knows, hehe!?
Cannot wait to find out, to read more that is, so please do update soon...
Author's Response: Thank you! I'm so glad that you enjoyed the first chapter and it interests you. I can't really tell you who he is exactly, but I'm sorry to say that he isn't related to Regulus and Sirius. He is a pureblood, though. And did come from money. Keep an eye out for the next update for more! Thanks again! :D
