Synopsis: The Leprechaun Prince

Maybe there is a secret country of redheads who lived in the Hollow Earth and emerged only to buy makeup. Some times they emerge for other things. Like vintage dresses. Our heroine (yet to be named) happens to fall down a hole into their lair and fall in love with the handsome redhead prince who will save her from being eaten (since the secret redheads are cainbals, of course). Then she and he will flee to the Upper World where they will have adorable redheaded children and lots of vintage clothing

I might have to work up to the conclusion some.

It's like chick-flick meets late-Victorian exploration-adventure novel.
