My name is Elyssia and I wrote a book on Booksie called Ellie and the Marauder's Map. I was unable to get into my account for three years and started a new one. unable to get into that one again. So long story short I am bringing here. 
The story is updated and slightly changed due to a new writing style and myself getting older. 
What Elyssia and the Marauder's Map is about is a self inserted fan fiction. You the reader follow me around my first year at Hogwarts. It is the same year as Fred and George's first year as well.
I will be continuing the fan fiction(s) as a book series leading up to the end of Harry Potter and the Deathly Hallows.
So join me/Elyssia Sage Caffory on her adventures in the Wizarding World of Harry Potter!
