This collects the entire J. Michael Straczynski run on Thor. I also enjoyed it very much, although I wish JMS was allowed to finish the story he wanted, but Marvel is obsessed with having huge events every 4-6 months.
That is what I have in Vol. 1-3. Issues 1-12 and 600-603. I am talking about issues 604-606 that does the conclusion of the Asgard in Latveria story. The series goes all the way to issue 621, there isn't a trade for the issues after 603?
