If it is possible, I'd go back to and read all of Jason Aaron's run on the Thor titles.
Here is where it began -
http://marvel.com/comics/issue/44198...thunder_2012_1
The
Thor, God of Thunder title went for 25 issues, then it relaunched as just
Thor, which introduced the female Thor. There were 8 issues of that comic before it ended and relaunched once again as
The Mighty Thor, with once again a new #1 issue. That is the series that is still going today. All three of those series constitute a single run of Thor comics all written by Jason Aaron, covering the last 5 years.
