I already posted this one in the
Graphic Novels thread.
A fairly quick read, but great nonetheless. It's an alternate-reality/possible-future type of deal. It's set 50 years after all the villains got together and absolutely fucked up the good guys. Wolverine is obviously the main character. I don't want to give too much away because its pretty sweet not knowing exactly what happened and getting that "holy shit" feeling when you get to that part. Basically, they fucked Wolverine up so badly that he became a pacifist and didn't use his claws once in the 50 years since the incident. A lot of characters are mentioned/involved. I highly recommend it.
