Getting a publisher to accept, print, distribute, and market your book has always been a difficult thing to accomplish. That is perhaps more the case now than it has ever been before.
You have another option, though: you can follow the lead of Mark Twain (and many others) and self-publish your books. And it's not as hard to do as you might think.
There are no "caveats" here about the title of this book: You definitely CAN publish a book with CreateSpace at absolutely no cost to you - I've done it myself several times (just a few of these appear on the cover of this book) and, in fact, I'm doing it again with this very book.
This guide is as authentic as it can possibly be, because it documents going through the process of publishing an actual book (this one) step-by-step, with screenshots to illustrate exactly what you will see and need to do in order to quickly get your book "out there" and available to a worldwide audience.
