Rating: Okay (Hated-Disliked-Okay-Liked-Loved)
Much like Lou Cadle's later series (Dawn of Mammals, which I just finished), this book is about survival. In Gray, there's an Event. Something happens. Luckily a woman had been about to explore a cave, so when fire started falling from the sky, when all the land burned around her for days, she was able to survive by going deep into it.
When the world finally cooled enough for her to come out, everything was covered with ash -- gray. Almost everyone was dead. Almost all animals were dead. Everything was gone, burned to the ground. And she had to survive in that world alone.
One of the big differences between this series and Dawn of Mammals was that lack of other people. (And, you know, the lack of interesting prehistoric animals.) That was pretty significant, as without others to interact with, we were just in her head all the time. For me, that made for a much less interesting story.
This wasn't a bad book, I just didn't find it anywhere near as interesting as his other series, so I gave up on it at the 50% point.
