How to publish a book?

Here are the steps you take:

1. Learn how to write a darn good story by reading books about how to do that.

2. Write the story based on everything you've learned.

3. Go back to fix the major and minor screw ups. (Like the main characters had brown eyes in chapter 1, but green eyes in chapter 8, you told the same thing twice, because you forgot you had already written that before, or you jumped over a couple of steps in the story to save space, but then you realize you need to show those steps to.)

4. Go back to revise your story to fit within all you've learned.

5. Revise, revise, revise, and then edit, edit, edit, until you just can't make it prettier.

6. Find other writers also working on their novels to critique their stories, while they critique yours.

7. Go back over your story, based on their critiques. (Revise, revise, revise, and then edit, edit, edit, until you just can't make it prettier, again.

8. Repeat 6 and 7, until they start nitpicking the most minor of things, because you can't ever make a novel perfect, or agreeable to everyone.

9. By the time you do all that stuff, you'll start learning just enough information about the publishing end of the business, to figure it out yourself most of the way, and for the stuff you don't get, you'll know enough other writers to ask questions. (This is going to be 3-5 years from now, if you hustle...longer if you dawdle.)

And, since you'll be an adult by the time you're done, age doesn't matter at this point.

There is nothing stopping you from publishing a book right now. The only problem you may run into is that because of your age, you may not have skill and experience to write something publishable right now. If your manuscript were to be accepted, you would need a parent or a guardian to sign the contract. If you really want to publish a book, do your research on what it takes to write a book and get it published.

Also realize that the odds of any author getting published. That doesn't mean that you shouldn't write but you have to understand you may never get published. You just have to keep writing. Kathryn Stockett who is the author of The Help said it took her 60 tries to get published.

Your local library has Writers Digest Magazine in it's selection, every issue, most especially the June ones, cover how to do it.

You can easily also google any writers sites, the publishing is continually talked about. Or do your own research with google using 'how to self publish', 'how to publish a novel' and 'how to publish with POD'. Amazon has it's own free publishing feature as well.

The basic warnings of not using a 'vanity press' still stand. They charge far more than just doing it yourself. Since all they do is print, not market the book, you're basically paying double for what you yourself have to do on your own.

The easiest way would be to self publish it as an ebook on a site like amazon.com, Which is pretty easy.
