Recommended Reading: Dark Reign
The Dark Reign banner was plastered on the covers of most of Marvel's comics for over a year following Secret Invasion, and the stories under the Dark Reign umbrella varied. Some were good, some bad and some had little to do with the Dark Reign story at all. This is my list of the good stuff. These are the issues I think are worth reading to get as much good stuff out of Dark Reign as Marvel offered.
The list is vaguely in chronological order as far as the stories go only because that is how I went through them in my head. This isn't a serious attempt at a chronological list for Dark Reign.
Some Dark Reign-related issues missing from this list may have just been forgotten by me, but it's more likely that for whatever reason I didn't think much of those stories.
