If you liked "The Stand", "Lucifer's Hammer", "Swan Song", "Black Sun", or any other after-the-world-ends novella, you will LOVE "Dark Advent".
without going into too much spoiler details, this book does a very admirable and believable job of covering the Apocalypse and what happens to the few unlucky survivors of the End.
Hodge does a magnifient job with the characters in this book. I found myself genuinely caring what happens to everyone, whether I wanted the character to live or die. Hodge explores the depths of human depravity in a world where there are suddenly no morals or laws (or at least no way to enforce them!). It is an interesting observation on how society probably would behave in this situation.
It doesn't have the mystical/spiritual element of "The Stand" and doesn't just end with a mysterious Godlike intervention, the way other Apocalyptic novels do. There are no mystical dream sequences, nor is there a clear-cut Good & Evil presence after the End. Hodge lets the characters seemingly become who they REALLY are, underneath the makeup of civilization, which is removed in a most-forceful way (civilization, not the makeup!).
The ending is believable, realistic - given the scenario, and this book is an AWESOME read. If you are a fan of post-Apocalyptic literature, this book is a must-have.
