I have chosen to use the Kindle Direct Publishing (KDP) Select service, since it allows me to promote my book through free downloads once every 90 days. My first free book promotion period of five days ended yesterday. There were a total of 143 Kindle Downloads during the period. Interestingly, there was a huge initial spike of downloads on the first day, which dropped off precipitously on day two. After the New Year however, the download count went back up. (Perhaps some folks have a resolution to read more during 2015?)
Anyway, I'm hopeful that I'll get some honest feedback on Amazon and Goodreads to help me hone my writing skills.
