Yes this book is based on Revelations which is throughout the book. The storyline portrays the end of days, though the ending I do not believe in, the rest gives a idea of the evil in the world today and to come.
It isn’t always happy endings when needing to defend your property, faith and way of life. I recommend this series if you are a faith driven believer of the last days and the bible. I enjoyed the series, well written.
