In this story I'm looking for all the characters are AU. Meaning none of them are CSI's. In this one Sara is possibly I think a former College student who is lured into a life of slavery by Grissom and Ecklie. Apparently they have an M.O of preying on young college women and for slowly luring them into Slavery and may years later release them. The women usually end up fragile and some have to be placed in institutions for their on protection. Sara when the story starts has been bought by Lady Heather, who is trying to help reach her. You do see how many of the characters know each other. Sofia Curtis works for Catherine I think and wants to help take down Grissom and Ecklie.
Trying to remember if this is a society where BSDM is common place or if it's a secretive lifestyle. I think the story was finished but I can't remember off the top of my head. I think Greg is one of Lady Heather's subs. Wendy the lab tech is I think Sofia's lover and sub. I think Nick and Warrick may work for Catherine also. I think at the end Catherine gets her revenge on Grissom and Ecklie by selling them overseas.
I tried to look for it using Google before I looked to see of anyone had seen it on the site.
