I am a freshman and I've been trying to write a book since last year and I did, but I scrapped it completely lol. But this year I said I have to write something before I turned 15 this July and made my first work that I am actually happy with, I've covered every plot point I wanted to and ended it well if I do say so my self. But I only have over 50 thousand words is that too little? And If so how should it be expanded. (wrote this in a rush sorry lmk if you have questions)
