I've been trying to compile my fave stories by writing down one or two details in addition to the existing summaries.

Well long story very short I hate Windows 10, had a forced update and lost my open tab before I was able to write anything down.

So I believe it's on Spark but not a 100% sure....

What I can recall Sesshomaru is getting his house in order to mate with Kagome. He brings his brother back into the fold and introduces InuYasha to Silver Demonesses so he can choose one to mate as well as returning his inheritance.

I appreciate your time in looking.
