I have quite a few Syn Gates fics that I have written/am writing. I would recommend Changing Tides (which is completed) and the sequel Happily Ever After is Nothing But a Myth, or Two Months and it's sequel that I started called the things that matter most. If you enjoy my writing, feel free to check out the others. I also have one M. Shadows story, a smuttalicious one shot feat. Syn and Shadows, and some Alexander Skarsgard fics as well!
I have an original called Winterhaven and my favorite story rn is Tallulah by kahlo. Sorry nothing is linked but I'm on my phone and that's an awful task
If you want a7z, Twin Flames is a good one. I have created a collection for all my a7z fics which you can check out. The rest are original, my best works are linked in my signature sweets.
I have my story City of Evil that you could read? It's not fully finished but it only has less than 10 chapters left. If you want a completed story, it has a short-story somewhat-prequel attached to it that you could read that is complete :)
Only read it if you are into thriller, horror, fantasy,...demons? haha
Well first, I'm going to whore out my own. Filled With Syn or Marked are both A7X. You may have already read em so it's cool. Two other stories I like by the author SyncityVM are Maid For You and Bewitched.
