Not sure if this is a mistake or a clever marketing ploy at Amazon, but the first volume of John Gardner's famous espionage trilogy "The Secret Generations" is now priced at $0.00 on kindle. Jump on it now, this could be a 24 hour sale. You can thank me later.
Update: Ok, the price went back up to $2.99 after a couple of days. But it's still a bargain.
