Little Drop of Poison (ao3)
Amazonia_8 (63,275; NC17)
Summary: Castiel doesn't know how to explain what happened to him a year ago, only that something killed his friend and a mysterious Alpha appeared out of the blue to make it all go away.
Now he spends his days running a small holistic health shop in LA, unaware that a looming political decision will throw him back into the path of the stranger he's never been able to forget. But how are they supposed to navigate monsters, conspiracies, violent pasts and family secrets when the only thing their instincts care about is making them mates?
Comments: This was actually a really fun political intrigue fic. Oftentimes, fics like this can drag through the slower, research parts, but this fic has something to compensate for that: smut! Desperate denial-filled true-mate smut! And the political conspiracy side of the story and the hunter vs. non-hunter side of the story are just intertwined enough to keep the plot cohesive. Gabriel is pretty fantastic in this fic, and I loved Cas’ employees and the Balthazar cameos.
Sort of an atypical ABO verse where reverse discrimination actual came true. Omegas knocked alphas out of power and now the omegas are in charge and the alphas are oppressed.
Now if this were a movie or something, I’d say the resolution went just a tad too smoothly, but this is fanfic and all I really want is for these two numbskulls to live happily ever after so I’m not gonna complain.
