Books with confirmed demisexual characters
Here are all the books I know of with confirmed demisexual characters! (Meaning the word is used in the text, or else the author has said it.) With links to more info, including (in some cases) reviews discussing the portrayal of demisexuality. Also see Lynn E. O’Connacht’s Demisexuality in Fiction list and the “demisexual character” tag on AgentAletha’s Tagpacker list.
The Change (series) by Rachel Manija Brown and Sherwood Smith - Mia is word-of-god demi

Ace by Jack Byrne - Jake is word-of-god demi
A Gentleman’s Position by K.J. Charles - Richard is word-of-god demi
The Trouble With Tony by Eli Easton - Tony is canon demi
Jack of Thorns by Amelia Faulkner – Quentin (because @demigray has recommended this as a book with a demi character, I’m including it even though I can’t find author confirmation that Quentin was specifically written as demi)
The Pardoner’s Tale by Morgan Ferdinand - Nick is word-of-god demi

The Mystic Marriage by Heather Rose Jones - Antuniet is word-of-god demi
Night Calls (series) by Katharine Eliska Kimbriel - Allie is word-of-god demi (caveat on this one—the first book came out in 1996, before “demisexual” had been coined, so it’s being applied retroactively)
From Under the Mountain by Cait Spivey – Guerline is word-of-god demi
I’m also posting this list on a static page, and I’ll be updating it there as I find more books/more are written.
