I found the story but couldn't find the sequel. It's called Becoming Death. I checked TtH and it's not there at all. I found it at http://tv.groups.yahoo.com/group/WitchsLoveFanfic/message/7628

The only reason I was able to find it because I tend to save stories I like and I looked through all of them. I know I have the sequel somewhere in my computer but the search option isn't working for some reason.

I'll post again when I find it.
