Hi girl... I just read your book, and I think its off to a great start, buttt...........
I have noticed that when writers mention their ages, it like ..takes away the vibe of the book. For example, if someone finds out a book is written by a 12-year-old, a lot of readers might not be as interested. And, it can lead to people focusing on age-related criticism instead of appreciating the story. Again, this is my personal opinion, if it doesn't matter to u its fine.
