I love this book the six book collection is one of the best I have ever read. Usually the zombie books are based on an infection or a man made disease. But this was based on your soul whether you believe in God or not the attack was on your soul and in the book a man was brought back to life and the demon that took over his body and made him empty of his soul was cast out. So the cure was casting out the demon with faith. When the man told his story about how he was bitten and cured no one really believed him accept for the ones that witness the healing. So the healing is inside of us based on our faith, so our faith will determine what type of world we have to look forward to living in or we all can consisted empties.
