First of all, hi anon! Thanks for the ask! I don’t get many so it’s always appreciated when I do! 

Second, are we talking about the same drarry? As in Draco and Harry? If you haven’t stayed up half the night reading a 200,000 word drarry slow burn then you haven’t lived! There is a ton of fanfiction, literally tens of thousands of fics on Archive of Our Own. I’d recommend you go there and search the tag with whatever filters you want - it’s so hard to suggest some when it’s ALL sooooooo good! What sort of thing do you like? Let me know if you want specific recs, I’ll read anything and have over 1000 fics in my bookmarks!

I’m probably better off mentioning writers - they’re mostly all on tumblr if you want to look but their fics are AMAZING. I started reading loads by firethesound (although stop all the clocks KILLED me so I wouldn’t read if you get sad easily) and then moved on to sprout2012 and Saras_Girl. I also love lomonaaeren femmequixotic noeon dictacontrion shiftylinguini birdsofshore and more recently bixgirl and thisbloodycat. Most of them are basically the gods of the drarry universe.They have written so many fics though that it will probably take you months to read them so choose carefully!
