I just finished reading this edition of the book tonight. Really good stuff here!
You can kind of tell it was made as a serial, but it works in the book's favor. All the chapters are short and crisp, with lots of action to keep the story moving. The first third or so of the book actually feels like a collection of interrelated short stories based in the same locale, with various characters from previous chapters stopping by to make cameos. A reader might have trouble keeping a few names straight early on given the speed with which new characters are introduced with similar backgrounds (namely, the P.O.'s and the military personnel); that said, when the core group of players emerges, it's an interesting bunch. All of them are very human, and appropriately damaged from what they've been enduring. And then there's Death. The Reaper is a strange one--part pulp hero right down to the white (okay, pale) horse and part lost soul at a crossroads. Better still, he's as confused as anyone as to what's going on.
Highly recommended.
