Miranda and Saba always fight on vacation. They even miss the ghost walk at their castle/luxury resort hotel because they're too busy arguing.

When they stumble upon a mysterious woman in need of help, there's no staff around, so the couple brings Oubliette to their room. Where did this strange girl come from? Why is she so dirty? What's with the clothing that went out of fashion three hundred years ago?

And does Oubliette have the power to reunite two lovers who’ve been at each other's throats all night?
