The Twelve is the second of the Passage trilogy. The way Justin Cronin had it, I am not sure the third book is worth reading.
As Passage ended, I expected the “hunt” to continue. I wanted those protagonists to bond deeper in their joined quest. Or, equally entertaining, would be a new plot Justin Cronin would come up. If the first of the trilogy covered a century, why not jumped even further and do another epic adventure? The first book created so many possibilities: mutation, battling, telepathy, virus and genetics, etc. I was really hoping for creativity. But Justin Cronin fell in love with his words and forgot about story telling.
The climatic battle was startling, nerve wrecking, and very satisfying. This book is really about the evil and dark part of the human nature. The vampires and their ecological struggle with the planet earth was reduced to the background.
If you have not, go read book 1. This book 2 will be optional. I will probably read book 3 just because.
