Kagome's Fateful Choice

After she realizes that Inuyasha has chosen Kikyo, Kagome returns the Shikon shards to the Sengoku Jidai in the dead of night, and vows not to return. But some choices are capable of setting everything on a different and darker path. When Kagome wakes up to an entirely new future, only she, with the help of Kikyo (who's now a part of her soul) can set it right. X-posted from AO3
