I really like Smashwords.
I've done all the Days of Madness E-books on this site and, when I wanted to share "Gathering Darkness" beyond the Amazon veil, that's where I went to first.
It's by no means a perfect platform, and the store itself could use a little sprucing up, but for those authors who want to share their work, and get it distributed, I haven't found a better way.
So - this week, Smashwords is holding "Read an E-Book Week". This event promotes E-Books as a great way to read your stories, novels, novellas, etc. on your favourite device, and it promotes indie authors and self-publishing (two things I feel very strongly about.)
As a participant in the event, I am offering my short story collection, "Gathering Darkness" for FREE all week - but it's a Smashwords exclusive. Link here.
(And while you're there, you can also pick up any of the previous Days of Madness books that you may have missed - also free - also AMAZING.)
I'll be back on this page and Facebook soon about this year's Days of Madness details - so stay tuned!
