I'm 13. Do you think I can get my book published?

I've written a couple book and I am a little iffy about them. My friends like it but they would say that they did even if they didn't. I'm not going to post it because it's too long though I did post the preface of one of them already. Anywys i need a little encouragement because things aren't looking great. can a 13 year old get a book published?
