I had a hard time rating this. I flew through the book and the characters were very interesting. The book was more about human interaction and the day to day of the survivors rather than about the event. I liked that but I was left wanting to know more. It's like the Author developed the characters extremely well but forgot that the plot is just as important. I gave it 3 stars but I probably would give it 3.5 if it were an option. The book was intriguing and kept me reading but I felt a little let down with the overall story. I can appreciate the Author and his easy going writing style that made me fly through the book.
