Due to navigation issues, I'm no longer publishing directly to Amazon.
I'm sorry for any inconvenience this causes people buying my books, but I feel it's the best choice for me.
My books are available in all formats Smashwords offers, so they are still available for you to read on your Kindle if that's your prefered way to read ebooks. Smashwords even gives instructions on how to get your books on to your eReader (if you need them).
Also, Smashwords does distribute to Amazon... Assuming Amazon feels I've sold enough books to be worthy of acceptance by them.
