A while ago, I wrote a book. It has finally appeared; you can pick it up here or here.
A couple of things on the Amazon page for the book surprised me. First, if you buy it from them and don't like it, you can trade it in for an Amazon gift card worth a whopping $0.75. So really you can't lose.
Also, there are already 7 used copies you can buy... though the book only officially came out last week. (Strangely, one of the copies is over twice the price for a new copy.) I don't understand the world of booksellers.
