I can't remember if I read the story on here or ff.net
But just as a warning, I didn't get to finish the story
so here is what I know....
The plot is....
Kagome is some kind of child protege/genius. Her father abused her and would basically "sell" her to any scientist that wanted to experiment with her and her abilities. Her father dies and so she starts to pick her own experiments she will participate in as a way to help her family with money. She gets pulled down the well and eventually ends up "adopted" by Sesshomaru's parents. I can't remember if Sesshomaru's father was actually called Touga or something else (also, Sessh's mom is still mated with the father). Sessh Mom gets a visit by Midiorku revealing that if she had lived, Kagome would have been her daughter. So she considers Kagome her spiritual daughter (I think was the term).
Meanwhile, Sesshomaru's instincts are clamoring to mate Kagome and Kagome starts going through a heat cycle like a demoness would.
There were a lot of chapters but I didn't get to finish reading the story and I've somehow lost the story.
Please help?
