The New Half-blood Prince

What if Lily paid more attention to the goings on in the wizarding world and realized that morality will get her and her future family killed so she took advantage of her perceived brightest witch of her age innocent muggleborn girl persona. This story is how this changes Harry and the wizarding world. This story is Dark with a capital D. After the first chapter it will be relatively not dark but might have dark elements like an enslaved muggle here or there. With strong cult themes.
