Mommy's Little Savior

Elena Hartwell wanted to stay with Killian Thorne, her boyfriend from college. Her uncle Victor was in a position to hurt him, so five years ago she ended it and left Killian believing she had been after his money. He went back to his family's business empire. Victor then framed her for a crime and she was sent to prison, where she gave birth to a daughter, Luna. Luna is four now. She finds her way to the headquarters of Killian's company and calls him Daddy in front of everyone there. A DNA test confirms it. Killian goes back through what happened to Elena, the conviction she did not earn and what she gave up to keep him clear of Victor, and he starts putting his company and his money into getting her out of prison, keeping Luna away from Victor, and having Elena back.
