Bring it On: Why Isn't My Book Selling?

I suppose I'm in desperate need of some advertising.

That, or I just need a little more gumption. However, I am proud to announce that I did do a fair number of Organic Chemistry problems this afternoon. We're going over reactions of alkenes.

So, perhaps it's not gumption I'm lacking. After all, I did just agree to a trade: a review for a review. Also, I think I'll be nice and post that Redditor's book here. Not that it will benefit him any.

Speaking of which, would anybody be so kind of to review a book of mine?

I digress. Despite the start, this actually isn't a "I'm a new writer and I'm not a best seller!" rant. (However, how fantastic would it be to be a best seller two weeks in? I would be jumping for joy!). No. Actually, I'm writing this because I am confused. Why? First off, let me note: I haven't sold a book since Saturday, and Chapter 1 of The Night Life, though free, has had only about 120 downloads in 4 days in Amazon's US store. For comparison, The Dowry had about 750 downloads on the day I made it free.

If you're reading this, you're either thinking, "But KT, what's up? You've only been published for three weeks! Why so impatient?" or "Who are you? I just stumbled on this by Googling SOPA!" (Alas, that ship seems to have sailed with Blackout Day.)

Really, though, I'm confused because other people say it's good.

From Kindle Boards:

KT:
Your blurbs and samples are too good not to draw heat.
They are tight. They pop.
(Are you having us on?)
Give it another day or two.

Also:

I took a look over your books; they both appear to have great covers, and the sample chapters were well written and interesting. 

And from Reddit:

...this book looks interesting. I loved the sample. I think I'm going to buy it.

Okay, that all seems well and good, right? Sure, it's only three people (I actually had one or two more buried in Reddit comments), but still, if three people are personally messaging me to tell me that the book seems interesting and they loved the sample, what about the people who see it and say nothing about it?

Oh, look, a suggestion appears!

I did notice that you haven't got any reviews up however. I was selling one book week basically until I got three or four reviews up; you really want to reach that 'five' number. Ideally they should be four or five star reviews... and I honestly prefer a scattering of fours (which is all I've gotten), since I think that means they're being critical.

So, is that what it's going to take, eReaders? You want me to solicit people for reviews? Well, if that what it's going to take, then bring it on.
