Pitch black m/m book recommendations

Oky so I just read painter's obsession which holy fucking shit darkest thing I've listened to so far and now I need more

So I'm looking for pitch black m/m books with the same vibes

It needs to be really dark like listening to the audiobook sends shivers down ur spine

It needs to be m/m please that's important

I don't care about trigger warnings obviously but if possible no golden shower stuff like that I can handle most stuff like legit torture and gore but bodily fluids is apparently where I draw the line

It definitely does not have to be HEA like the one mmc can die or both or the mmc can escape

Point is I want it really dark like listening to it will make me sit down take a breather and go what the absolute fuck did I just listen to

And preferably duel pov please

But I cannot stress this enough I want pitch black destroy ur sanity dark!

Thanks guys!💖
