Free Gender Bender Plot Idea

#1
I am not a writer by any means but, I have had a Idea for a novel and was hoping someone would go with it. So here goes.

There once was a king or demon king that wanted a wife and did not like any of the princess's of his world. So he decides to use a forbidden spell to summon a girl from another world to be his wife.  The poor unfortunate sole happened to be a man in the other world but was transformed into a female to spell when summoned.  This summoned character will hate the king/demon king for a long time but will warm up to him slowly and eventually fall in love with him.  There could be political intrugre and action in the story as well.

Anyways I know its a long shot but I was hoping someone could take this idea of mine and make it a novel.  I am not good at writing stories and prefer to read them.
