Could anyone tell me what are the best TVD fanfiction novles?

any user in tumblr you could recommend?

No, sorry, unfortunately I have no tumbler so I don't pay attention to users, however you could search on Google "Damon and Elena tumbler" and the latest topics will appear. And of course you could go to the easy way with fanfiction.net. there you can categorize your search as vampire diaries, then narrow it down to Delena. You can even choose for it to be sorted by name, or date updated, or date published or most reviews. There are also communities there, you can also narrow down your search for communities concerning Delena and there you'll see ppl posting the best fics avaiilable on the sites. And I'd search for underrated stuff, sometimes you fine the BEST there.

Thanks, this actually helped a lot
