Is it a novel?
What's it about? (Have you finished a first draft or second draft or....?)
How to get published depends partially on what you're writing, if you know anyone who can help you, if you can get someone to help you.
How long is it?
And can you compare it to another book, sort of a If you liked this then you'll like my book.
That's not too long - I can read that for you.
I'd love to read your book! I'm 19, so I believe I will be an accurate age group for you to test on. I'm not going to be nice with my critique though, but I'm not trying to be mean, my review would be useless if I didn't tell you what I honestly think of it right?
I'd love to read your book and then I could give it to my teenage daughter to read so you could get feed back from both old an young.
