Carina publishes M/M, quite a lot of it, and has for some time. They *are* more well known for contemporary romance, but that's across the board, not just m/m. I'm sure they'll take a fantasy m/m if it's what they want.
Disclaimer: I'm an author with two m/m romances out with Carina, and an m/f with a tran guy romance coming out next year. But hey, what do I know about publishing with Carina?
ETA, because I'm annoyed, I'm just gonna point out that 4 of their 6 coming soon titles are m/m. But hey, I guess they don't publish much of that.
And hey, Annabeth Albert's m/m holiday romance came out with Carina today and it's currently #44 in Gay Romance on Amazon, but I guess Carina isn't a viable place for m/m, right? Ho hum.
