25-year-old One Direction fan Anna Todd just landed a six-figure advance when Gallery Books, an imprint of Simon & Schuster, bought the rights to her One Direction fan fiction. Excuse me, her erotic One Direction fan fiction.

Todd posted the story, titled After, on the fan fiction self-publishing site Wattpadd in 300 daily installments, spread out across three volumes. The story took off instantly, gaining more than 800 million reads, and leading to fan-generated art and playlists on Twitter and Instagram. Billboard reports that Todd's writing even led to an increase in popularity for other pieces of fiction:

When Todd mentioned "Pride and Prejudice" or "Wuthering Heights" in "After," Wattpad had spikes in the reads (how the company counts clicks) on those novels on its site.

Hmm. Never heard of them! In an interview with Sugarscape, Todd explained how she began writing 1D fan fiction:

It really started when I was on instagram one day, and I saw these little mini stories people were writing about Harry Styles, which was crazy to me. Then one of the girls I had followed on instagram put her story on Wattpad. I had no idea what that was, but I followed the link and it was this whole world of 1D fan fiction. I started reading all kinds of it, and then decided that I wanted to give it a go myself. I didn't think anything would come of it though - it was just for fun!

And here is Wattpad's description of the work:

Tessa Young is an 18 year old college student with a simple life, excellent grades, and a sweet boyfriend. She always has things planned out ahead of time, until she meets a rude boy named Harry, with too many tattoos and piercings who shatters her plans.

MTV reports that—in case you were worried—After is also being shopped around to movie studios.
