Romances with an asexual character

[Tathariell]

I just read a romance novel, and one of the side characters was Ace. I haven't seen a lot of representation in fiction, and would love to read more! Any genre is fine, romance preferable. Bonus if the main character is Ace, but I'll try it for side characters. Please only recommend books with actual characters who are Ace, not someone mentioning they heard about this person "off screen".
Spoilers are fine, it's okay if the character doesn't come out until further into the book.

(some of these have sexually explicit scenes, but they all feature at least one main lead on the asexual spectrum)

Vanilla
Tash Hearts Tolstoy

[Fani *loves angst*]

Feral strongly implies that the hero is asexual. It belongs in the m/m romance genre.

[SamSpayedPI]

Blue Steel Chain (part of a series, though, the others of which are not ace)
Demonica (very short; more of a story than a novel)
Heartsong (again, part of a non-ace series)
His Quiet Agent
More Than Enough
The Rat-Catcher's Daughter (I admit I haven't read this one yet, but it's a prequel to Any Old Diamonds which I liked a lot)
Upside Down

Loveless by Alice Oseman

[Rainbowheart]

I thought in Loveless, the MC definitely is not interested in romance?

[Gillian]

It's not the main focus of the book (not even close!), but the main character is ace in Every Heart a Doorway by Seanan McGuire if you're starved for representation (like me.)
