is there a novel about a priestess ended up loving a man?

If you put your ideas like this in open it wont be original anymore dude! you just did a mistake dont repeat it again!

If you think you have a story write it. There are always stories with the same idea. but they all end up different. Good luck.

There are very rarely new ideas about novels. If you want to write a story then, go for it. Your story will be original regardless of whether the type of characters is unique.

There are many stories like this in the mythology of almost every culture. There are stories like this in Shakespeare. There are stories like this in legends and in history. The point is, it's the way you write it that's original. If we all tried to write only what has never been done before, nothing would ever be written!

Go for it!!!
