I've got a lot of novels, one could be called BL as a sub-genre, but I feel like it strays from a lot of the tropes of a lot of BL stories, so its listed as an LGBT romance instead. It's high fantasy, so my own little made-up world, the two characters are princes whom belong to two kingdoms at war with each other and have been for decades. One of the princes, a fairy, finds the other prince on his kingdom's land, horribly injured and close to death...so the fairy prince decides to take the injured one in and heal him...the other prince offers a relationship to stop the war...does it work? Well, you'll have to read the novel to find out.
