My good friend and fellow blogger Mike Mollenhour has decreased the Kindle price of his second novel, Amazon Avenger, to just $0.99. If you like Tom Clancy-style thrillers with realistic gun play, then I highly recommend this book.
On a side note, if you have never tried using a Kindle or similar ebook reader, please go into a store and try one. Even when publishers offer to send me free books I instead opt to buy on the Kindle because the reading experience is so much more pleasant.
