Make it this one! Seriously, go read this story. It's called "Tales From the House of the Moon", by Resmiranda. It's an Inuyasha fanfiction, starring Sesshoumaru and Kagome. Don't let the pairing fool you! This is the most beautifully written fanfiction I have ever read, not because it's romantic (which in a very literal sense it -is-), but because each situation in which the characters are placed draws you in.
Anyway, to see what all the fuss is about:
Tales From the House of the Moon
Note: This is a very long story. Just call it a novel, really. I suggest printing this out so you don't have to strain your eyes on the computer. H
