Ed's "How to Format Your Novel for Kindle, Nook, the iBookstore, Smashwords, and CreateSpace...in One Afternoon" is probably one of the most useful books I've ever read throughout my entire indie carrier. I've spent years cursing and grunting over word processors, and I've always get less than half of what I expected.
As soon as I switched to Scrivener I heard incredible things about the magic book that, apparently, transformed your work in a fantastic eBook (and much more than that).
I was skeptic, but for the price I guessed it deserved a try. I had never used Scrivener, but Ed's book allowed me to create my own eBook in one hour. I couldn't believe it. In one hour I had done what it usually took me a week or more. And it was stupendously easy.
I'm not sure if this book may be useful for those who already master Scrivener, but I can't recommend it too much to the legion of self-published artists out there who struggle with the conversion process.
Another thing worth mentioning. I had some questions when I was compiling my file and I sent them to Ed via email. He always answered within the hour, proving his commitment to stand behind his product. This is something I really appreciate and that you don't find as easily as you may expect.
To wrap this all up, if you don't have Scrivener, buy it and with this book you'll go to the next level. If you can't use Scrivener because you don't have a Mac, buy the Mac then get the other two things. I know, it sounds crazy: buying a 1000 plus dollars piece of technology for a 45 dollars program?
It's worth it, and with Ed's book even more so.
(I know Scrivener runs on Windows too, but apparently there are some differences between the two versions).
