Skreemer's the first American comic Milligan did and one of his rawer works. I usually compare it a bit to V for Vendetta, both in content as in the work when looked at as a certain point in the writer's career. It's about an era where the city (world?) Is ruled by one big crime boss (the Skreemer) and it follows his rise to power, his possible downfall and the life of a normal man who suffers a lot in this rotten world. It's a raw masterwork, although it's pretty polarizing among the general comic book audience. I really, really love it though and see it as one of the best mini-stpries ever made. I really recommend giving it a try. Shade's almost entirely collected but the tpb line was cancelled 15-ish issues before the end (dick move from Dc). Enigma has a readily available tpb but sadly no hc. Milligan is severely underrepresented in the hc area, we really need more of him.
