I'm planning on launching my debut novel "House of Mirrors" within the next two weeks, so I'm looking at all of the available platforms. So far, I'm sold on trying Amazon's Kindle Select first. You have to make your book exclusive to Kindle while enrolled in the program, but considering that's where most people do their book shopping, it makes good marketing sense.
I researched the various platforms available to indie authors, and I posted it below for others who are not interested in making their e-books exclusive to Kindle.
