Foldes

I should like to know if someone can recommand me a novel who has a good romance, i want one who is set in a medieval age or in a fantasy world. If there is some no-human heroine like elves, angels or kemonomimi should be nice to, and i want a traslated novel, or a way to read novels in japanese (maybe a program or a way to traslate it by my self is fine to, i want to learn the japanese anyway even if i don't find a way to). And i prefer if it's 18+. Thanks since now and waiting anxiously.
