Hey Steve, I was in the Amazon Kindle Books section just now, searching for "Firefly" (an awesome US tv sci-fi series) novels. And guess what? Your book,
The Kestral Voyages: Berserker, was on the first page of results, number 8 on the list. Three pages worth of results showed up, so your's being on the first page is pretty cool.
So the good news is I found your book without looking for it at all, so potential new customers there. Bad news is no Firefly novels. But there was a novelization of Serenity, which is the movie based on the Firefly series.
Anyway, thought you might like to know that it shows up fine and dandy. I was surprised to have it pop up when I searched for Firefly.
So remember, don't go hatin' on the Kindle, because there will be lots of Kindle people buying your books!
