You need a lot of practice writing in 1st person POVs, you keep going back to normal POVs. i.g., "I was sent away when she was younger to go to a proper school for ladies", see how you start with "I" then change to "she". You do this a lot with Sess too. Then in your Sess POV, you have Kags thoughts come through which makes it seem as if Sess is hearing her thoughts. See? You need a lot of practice or at least a beta.

I love it so far! I can't wait until Kagome and Sesshoumaru meet and I do hope that Kagome isn't too in love with Inuyasha. I'm also concerned about Zuka because Sesshoumaru seems to favor her of some sort. She's not gonna be a major conflit between the two, right? I hope not! The story looks great so far too! Keep going!
