False Gods, by Graham McNeill

This is the second in a series based on the Warhammer 40,000 universe. It continues the fall of a near-mythic being created to protect humanity from the dangers of intergalactic space in the distant future. I wrote this about the first in the series, by a different author, but it's true of this book as well: For what are essentially tie-ins, these are remarkably meaty reads. There's very much a Christ kind of thing going on, but in reverse. Horus, a nearly unstoppable warrior, is laid low by treachery. He's brought back with the help of a handful of followers, only his time in purgatory left him with some ideas that will have dire consequences for humanity. It's a must read for fans of Warhammer, and also a great read for those into space opera in general.
