The story details a cometary impact on Earth, an end to civilization, and the battle for the future. It encompasses the discovery of the comet, the LA social scene, and a cast of diverse characters whom fate seems to smile upon and allow to survive the massive cataclysm and the resulting tsunamis, plagues, famines and battles amongst scavengers and cannibals.
So far it's a pretty good book. The reading gets a little bogged down in some areas but overall the authors do a good job.
4 stars from me.
