I don’t want this to come off mean, but you’re book needs quotation marks, it’s too hard to read, trust me, ima read it either way because it’s just too good, but it would be helpful.
You said that you have been writing since you were little. How old are you now?
So far your plot isn't too bad, I have used genre stereotypes and old ideas too. It is how you bring your own twist to an old story that matters.
Some of your writing is weak, I admit. Practice and reading above your grade level will help.
I wish you luck. Keep it up!
