Queerceañera by Alex Crespo was a cute romcom.

The Sunbearer Trials by Aidan Thomas had a similar appeal for me as the Last Airbender. It’s much more adventure than romance.

I liked Waiting for the Flood by Alexis Hall, but I wasn’t into the sequel and haven’t tried anything else from him yet.

Most Ardently by Gabe Cole Novoa is Pride and Prejudice with boys, though the author is non-binary in this case.

Even though the authors are women, I have to recommend Notorious Sorcerer by Davinia Evans and Self-Made Boys by Anna-Marie McLemore.
