I am 13 years old and I am a dedicated reader! I love to read people's works and telling them what I think of them, but be aware of one thing: I am brutally honest. If I like it, I will say so. If I love it, I will say so. If I hate it, I will say so. But I LOVE to help out new authors with those kinds of things. 
If I say I don't like the book, I will definitely say why. I would never leave anyone in the dark about why their book isn't very good. If I say I love a book, I will say what I liked about it, so you can keep up the good work.
If you want me to help, you can either message me on my profile or kik me. I will answer faster over kik, though. 
My username is fantabulistics (I know it sounds super weird, but I made it up a long time ago.)
Anyways, good luck with your writing! ILY ALL!
