Wow. This was the final volume in the series. I haven't read #1-3 yet, just picked this up from the library shelves not having any idea what it was about. Now I want to pick up the other volumes to see what I missed. Not having read the first three volumes, I still didn't have any trouble with figuring out what's what and the final conclusion was still pretty intense. Dark, brutal, super-hero/sci-fi/spy noir. Good stuff. Read it.
