Now, it is worth noting that if you want the FULL story, you'd have a pretty big task ahead of you. It'd require reading about six years worth of material. So, let's skip that since it's not really a reasonable expectation for myself nor for anyone this is in the target demographic.
All of the following are available now.
1. Avengers #14
2. Asgardians of the Galaxy #6
3. Thor #10
4. Avengers #15
5. Avengers #16
6. Asgardians of the Galaxy #7
7. Thor #11
8. Avengers #17
I'll be reading and posting reviews for these in the coming weeks. I doubt I'll be doing the side stories once the event starts, but I hope you consider doing the same and reading the above books. Issue one of War of the Realms is on shelves April 3rd. If you'd like a more, in depth list you can find one here.
