The Once and Future Taiyoukai by RosieB
The well was supposed to be stable. It was supposed to send her to Inuyasha. And it failed. Now, Kagome's even farther into the past and she must depend on a young Sesshomaru, who has no idea of what their shared future holds. But neither does Kagome.

Kagome is saved by Sesshomaru. Unfortunately for the young miko, Sesshomaru’s version of chivalry includes having her impaled by Tenseiga and thrown down a mystic well. But that is only the first of our miko’s problems. SessKag
