On June 6 I uploaded Unbridled Love: A Romance with Horse Sense to Smashwords. Since then it has slowly filtered out to other booksellers and is now available for Nook through Barnesandnoble.com and for iPad through iTunes.apple.com.
I don't know how many copies it's selling in these other formats because Smashwords reports and pays royalties on a quarterly basis, but it's already my bestselling title in any format at B&N. At the same time, it continues to be my bestselling title in any format at Amazon.
Watching the steady sales of Unbridled Love and comparing them to the hit-or-miss sales of the other titles I've self-published makes me think I should consider writing another sweet romance involving horses.
