I am really enjoying this so far. I just discovered this fic this evening and read from start to this point.
One thing I noticed, and it's not your fault, it is a formatting issue. If you look at the drop down for the chapters, it goes 1,2,3,4,4,6. So when you hit the little arrow to go to the next chapter and you are on chapter 4, it doesn't take you very far heheheh.
Anyway I really am enjoying this.
