Note that I'm writing here as a reader, not as someone who has tried self-publishing...
The thing is I dont know how to promote it. I paid for a promotion and it only got me one sale. It's so depressing.
What promotion? Where? With whom? I read in a book on self-employment once that, when starting a business, you should ask yourself how a stranger coming to town who wanted your goods or services would find you. If the answer involves a miracle, you're in trouble. If you read romance yourself (and I'm assuming you do), how do you find new titles to read? Are there blogs you trust with recommendations, or reviewers you like, or message boards/discussion groups on social media? Was the promotion you tried one that you yourself had responded to ever as a reader, or was it just a random shot-in-the-dark attempt?
I get a few of those daily discount e-mails (Bookbub, etc.), and I can tell you that a good, quick, hooky blurb is more likely to grab me than a long, meandering setup that requires me to click through before I even know what the book is about or why I should care about anyone in it. So consider how your book is presented in whatever promotion you're trying.
And about .99 ... if no one is buying with this low price...who would with higher...
There's a saying that, paraphrased, says that if you set a low value on yourself, don't expect the world to raise it for you. If you believe in this book, and believe it's solid, why throw it in the 99 cent bin? There are many, many romances in that bin... and, from personal reading experience, some of them would not be worth much more than that, and more than one I felt I overpaid on, to be blunt. A higher price gives the air of higher quality to the average reader. (And a higher price, offered at a temporary discount, gives a sense of urgency that might drive a few sales itself: I'm more likely to bite on a "maybe" title under those circumstances.)
And I'm offering free copies for romance readers but so far no one even replied with a No...nothing. I dont think my novel is so bad... but if it's allowed here I would give you the amazon link ...there's almost four chapters preview...
Where are you finding these romance readers, and how are you offering the freebies? Random spam often ends up deleted.
Incidentally, I came here looking to see if I could find a link to your book (expecting it, actually, if you wanted help with promoting), and I found nothing. Right there's a click you lost - and without a click, there's no sale potential.
