Damaged Defenders by Sherza

Awesome, awesome story that follows the line of what if Thor was smarter & faster to realize that Loki was being controlled, what if Phil, Natasha & Clint didn't trust Fury, what if Tony played Fury and decided to call in back-up in the form of the X-Men, what if the Battle of New York went differently. You would have this awesome take of a group of damaged people who will have to step up to unite the world because that was only the first strike and war is coming. I have to admit I was leery of the constantly changing viewpoints but with a group this large and complicated you almost have to. The author makes it work and there are some scenes that just wouldn't work as well such as the scenes with the Winter Soldier. Slowly other characters are being pulled in and this is going to be huge and ongoing for a while but so worth the read.
