Can confirm, I work in both a library and a bookstore and Red Rising is shelved in adult sci-fi in both places. Don’t know why the OP thinks it’s YA.

If there are more blurbs than legit reviews, then I get concerned.

Book banning is the new Satanic Panic

The Dreaming in Neil Gaiman’s The Sandman. Places like Cain and Abel’s House of Mystery and House of Secrets. Places within a fantastical, shifting landscape.

Honestly, same. Fell in love with Anne Rice’s works as a teen, but stopped reading her stuff published after 1998. I think this is also around the time she stopped letting editors touch her books, which contributed to the decline.
