The only really good one I've read was lighthawkdemon1's story
A Change of Heart. I've read a few that were halfway decent, but not enough for me to go out and find them.
I also have my own 'Inuyasha/Kikyo' story...sort of. It isn't really an Inu/Kik in that, it is mainly my Gerry Stu OC/Sango (
I'm actually trying hard NOT to make my OC character a Gerry Stu. But if you read it at this junction, you certainly would think he is!). Inuyasha/Kikyo is there kind of a background relationship to it. Though given that it is my LEAST read story, expect this story to be low on my update priority list.
