Digital comic book distributor Comixology is getting into the holiday spirit by offering a different title for free each day through December 20. Each comic is available for one day as a download both through the Comixology website and the free iPhone and iPad Comixology app. The first two titles were Batman: Death of the Family issue 1, and Lazarus issue 1. It's a fun and easy way to try out digital comics, and might expose you to titles you haven't seen before.
