Aro/ace book recommendations?

Ideally aroace, but only aro or only ace is fine too. I want to read main characters that are like this, and their orientation must be an important part of the book (not saying the plot has to be centered around that, but ya know). Thanks in advance!

EDIT: Forgot to mention I've read 'Loveless' already! The only book with aro/ace representation I've read, which is why I want to read more.
