I've really enjoyed this story. It's well written, and I like how Harry is a Slytherin without being a jerk or a Gryffindor wannabe. He shows traits from all Houses with cunning and ambition being at the forefront. He interacts with all the houses and even with his plans he makes no secret of where he stands on Voldemort. Definite harem especially with Daphne, Tracy and Hermoine.
The only question I have is about the last chapter. Did you take it down because there was a problem? Whenever I've tried to read it it comes up blank and I would like to read it because it sounds great.
