I cannot say enough good things about Smashwords. My book, THE MAZE, is already in the Premium catalog. The cover wouldn't take and I didn't like it anyway, so I did one in Powerpoint in about ten minutes and, though it is not my favorite, it is in keeping with several of the book's themes and doesn't look bad. I wanted that little red head on there from the get go, but couldn't get her to fit. She is a joyous me, someone I don't see too often.
A person was sorry they couldn't download cuz they had a Nook. Anymore was in Select and will be for a few more weeks, so that is Amazon exclusive, a mixed bag, but it will go on Smashwords too pretty soon.
Smashwords puts you in the Apple, Nook, Kobo, and all other devices format so you can even download to some off brand e reader you bought on vacation in Thailand. I have always had my best sales from Barnes and Noble, so I hope this works out. Hundreds have already been downloaded for free, and this book, which I love so much, I am doing the sequel, is in the cellar at Amazon. So I hope y'all enjoy it.
