This sums it up pretty nicely:
Last night at midnight A Brooding Beauty went on sale at Amazon for FREE! Since then it has sold
531 852 copies and the promotion is only half over (for those of you who are interested, ABB will go back to the usual price at midnight tonight, so get it while it's hot!).
It is also ranked
#39 #29 in the historical romance category (for free kindle). Before I think it was in the general vicinity of #1,359 (not that I was keeping track or anything).
Basically, the KDP select program rocks my socks. I'll explain more about the program later... when I pick my chin up off the floor.
