To make Maid for Love free I changed the price to free on Apple and Kobo and then reported it to Amazon, which matched the low price a few days later. To get the book offered for free on B&N, I distributed it as a freebie via Smashwords. It took a couple of days to show up on the retail site.
Prior to the free offering, the McCarthys were already my most popular books, selling strongly every month. After two and a half months of offering Maid for Love for free, they are even more popular. Maid for Love was the no. 1 free book for all of Kindle for more than a week in late June and remains today at no. 97 in the Kindle free top 100 and at no. 27 for free contemporary romance. All five of the other McCarthy books spent time in the overall Kindle Top 100 in June and July and all of them remain in the contemporary romance Top 100 today.
Here's a breakdown of the numbers. These numbers are for Amazon ONLY. More below on the results on the other platforms. To offer a benchmark of an average month before the free offering, the numbers for the series in May were:
Another interesting side effect of the freebie is the explosion in reader mail, Facebook and Twitter followers, subscribers to my mailing list and the members in the McCarthy Series Reader Group on Facebook, which has grown by more than 1,000 members in the last two months.
