The Adventures of Mo in Crossover

What happens when a girl with ADHD decides to write a book, make herself the all-powerful main-character, and decides to add her sister, with nothing but her imagination (and sister (editor) and the computer;...mostly the computer)? This book.
This is a Percy Jackson, Kane Chronicles, Magnus Chase, Harry Potter, and Adventures of Mo story/book/crossover (Adventures of Mo is my thing).
If you read the first sentence and thought that was what the book was about; you're wrong. Basically, I'm gonna force these guys together. Why? Because I want to. You are gonna learn a lot about my sister and me (grammar 😋) in this/these book/books. (Everything about us is true... minus the names, powers, and looks (my looks are correct at first). Oooor... 💥)
Also, I don't really know how to do a lot of things; so if you mention something that's only within Wattpad, you might need to explain it to me. I'm clueless 😜.
This is my first book and I'm kinda nervous.

P.S. I wrote the first... two and a half (?) chapters during the beginning of the school year (2019) I'm posting the book without finishing it first because I'm kind of stuck. (I was originally writing the story on GoogleDocs.)

Aaaaand I think that's it! Wait! This story takes place after Demigods & Magicians and before Trials of Apollo (since that series isn't, currently, finished). Oh! And, also! ... I forgot. But, if you point out something I did wrong and I answer, 'Heh, heh. *sneaky look*, then it's supposed to be like that (I don't want to give too much away)... Oh! I remember! (I'm sorry this is very disorganized.) All the characters are gonna be, like, 11. This is not 'back in time' or anything, I just hate it when they grow up. 😐 THEY'RE GROWNUPS! 😩 It makes it different. 😟 But we still younger. 😋 This must be so confusing...
