This story picks up the stories of the characters shortly after book one and delves a lot deeper into the world in which they live. We gain a greater understanding of the spiritual and theological background. We also get glimpses into ancient history of the world.
This book brings back more of the characters from the first book than I expected, but it is done in ways that feels completely natural.
This all builds toward a conclusion that will lead us into what should be a thrilling book 3.
