I am currently writing a Harry Potter fanfiction called "Snitches and Spectrespecs".
Once I have finished that, I'll continue writing a different story that I'm working on. Hopefully, it will be more intriguing and filled with more of my own original ideas than my current fanfiction. I'm aiming to make it into a book series, rather than a standalone book. If you enjoy magic, secrets and the blue academia aesthetic then I would recommend this. It will take longer to write this one because it will be more complicated but I'm very excited about it.
If those go to plan, then I will consider writing a fantasy quest book that I've already got character designs for. This one will actually be an original story, rather than a fanfiction. If you want to co-write this one with me (and if I know you IRL) then feel free to message me and I can explain what I've already come up with. If I get enough ideas about this story in the future, then I'll probably make it a solo project.
Thanks for baring with, I hope you found this insight excited and/or helpful.
In the meantime, I'll have to do lots of reading writing!
