The whole series is a good read and fairly bibical. It is a fictional work but stays fairly close to the prophies of Revelations. It tends to make a person think and welcome the coming events of our Lord and savior Jesus.
I had books 1 through 12 thinking that those were the only book sin the series. Little did i know there was an unnumbered 13! I saw this and had to get it, along with the 3 book pre-series. It was the first book i read and after an enclosed 3 hours, i finished it more than satisfied and hungry for more.
This was shown in our church one Sunday and we liked it so much we ordered our own copy to watch over and over again. Our oldest daughter (9) was quite impressed with the message and how it was explained.
