The North Pole and inner Earth Chronicles
Nice concept of having two books in one, I've only seen it done a few times. The two stories complement each other and have good tie ends to Genesis 6 scenario and pre-adamic, Atlantis. I've read a few similar books written by Steve Quayle and mainly collaborate or harmonize the concepts of the watchers and Nephilum giants. The first book written about the Norwegian fishing sailors really give you an idea of how rough the voyage was and how much tribulation they incurred, but then transition into a land of wonderment on the inner Earth and the friendly giants they met. Amazing!
The second book concerning admiral Birds encounter with human or alien entities at the pole makes a lot of sense and collaborates many other books written about this subject.
A very valuable book to have in your library, also I thoroughly enjoyed reading it. Very inexpensive. Sebastian would appreciate your support, check him out on Facebook.
