[Sunday morning update]
We’re up within 35,000 today, and there are three new (all five-star) reviews.
I think this is the highest ranking the book has ever had on Amazon. Sales must have picked up this week (I hawked it quite a bit while in DC, both at the conference and with a couple think tanks — I’ll probably be doing a ReasonTV interview in the next couple weeks).
Also, it’s once again number one in the category “Aviation and Space Law.” Plus, it’s selling for full retail, which I’d assume means that Amazon thinks there’s sufficient demand for it that they don’t have to discount (not that I’ve given them a lot of room to do so, but they have had it down a buck or so in the past).
[Update a while later]
OK, based on numbers at the printer, it looks like I sold 27 books last week. Compare that to 18 for the entire month of January. Hopefully those will continue to build with more publicity, and good reviews at Amazon (six right now, all five star).
