Yes, like the song from Les Miserables, but no,
it's not about Marius and Cosette.
This is actually a Harry Potter fan-fiction about Lucius and Narcissa Malfoy that I wrote several years ago and I'm about half-way done with it. It's actually one of my goals this summer to finish the story. I was playing around on PicMonkey when I had an interesting idea to make a promo. poster (yes, fanfic writers do that) for my story.
You can click on the poster to read what I've written so far.
It's definitely one of my favorite stories.
