"Hello! I finally wanted to take the time to write to you and tell you just how much I love your books. I truly adore them, your writing style is incredible, and I always look forward to your stories.
Today, I’m reaching out with a special little wish that is very close to my heart. I am an absolute fan of the Avatar: The Last Airbender universe (both the animated series and the movie!). It would make me really, really happy if you would consider writing a various x fem reader book for this fandom!
For the plot, if the idea inspires you, you could perhaps start by basing it on the events of the series, and then move on to or finish with the atmosphere and story of the film. Being able to read scenarios with different male characters and the reader, written with your talent, would be an absolute dream and such a gem to read.
I know that writing takes a massive amount of work, so please don't feel any pressure at all, but I wanted you to know that it would make me so, so happy.
A huge congratulations again for everything you write, and take care!"
