Your a high society noble woman. You have a mortal enemy- or rather, school yard rivalry, with Jack Taylor.

Before the debutant season, there's a massive masquerade ball where you can do anything you want and not be beholden to the rules of high society.

You go there, get hammered and sleep with a man. All you remember is his black mask, he wore a sword (odd for this generation), and what he did to you felt really good.

Sometime later, you find out your pregnant and- surprise! Thanks to a magic ritual/spell your friend did, you found out the father is your 'mortal enemy' lord taylor
