Well, I added you to my recommended reads, But i hardly think that is going to promote your fic enough. I still think you should go with my idea, because your fic has already moved way down in the list. You can watch the number of views carefully, and when it stops increasing, or only increases by 2-3 times a day, remove chapter 5 onwards and post them anew one by one, if you want, i can beta them for you, since i saw a few mistakes here and there, nothing too serious though.
the reason i am so keen about you getting the place you deserve with the fic is that i am a writer myself, i am currently writing a Drarry, and i am trying very hard to get the emotional depth and the plot and characterizations that i want, so i know how much time and effort goes into writing something so intense and to write 43 chapters of it and then watch it get pushed down by unfeeling and silly one shots and meaningless fics is just heart-breaking. I don't want you to get discouraged.
I am posting on a lot of other archives as well, i don't know if you are. There are a few active ones dedicated to SNarries. So may be you should look into posting on those as well?
