I wanted to ask this question to everyone.
I was 12 5 days ago and i tried to get my novel published. but not many people wanted it since i am so~ young and if you don't have really good telents, you would'nt be able to publish it at this time.
why don't you try getting it published by yourself?
Booksurge.com
go there. and they would tell you how to publish by yourself.
so in conclusion, no-one would get a 12 yr old kid's book published but that does not mean that yo have to stop trying and stop writing books.
keep writing and ger your skills buiilt up! maybe someday, you would become the next J.K Rowling!
hope this had helped.
