A week ago, Amazon released a new app for publishing comics for Kindle. I grabbed it to try it out, and published my 2010 comic project with Ben Bova and Bill Holbrook, called A Duel in the Somme. The app worked pretty well, and was easy to use.
Anyway, if you have a Kindle, the 24-page comic is available as a free download for the next few days. If it seems worthwhile, I'll convert Erfworld Book 1 soon, too.
