I'm trying not to be a crazy nutcase following the stats on my books at Amazon BUT I did come across this by accident- Murder for Profit is number one at Amazon today for books about Botswana. And Anything for Money and Claws of a Killer are in the top 20.
I'm really quite proud of this because I did it myself, it is so empowering. Often as an author you feel like you're at everyone's mercy. I try to make recommendations about how I think things might be done but it is up to the publisher to decide if they want to do it or not. In this case, I get to try everything I think might work and it seems like something is.
Enjoy your weekend. I'm off to see rhinos and elephants- see you in a week or so!!
