The Original Witch Store

Does a vast unknown area exist inside the earth? Are there entrances aat the noth pole? Are the world governments keeping this a closely guarded secret? Is this world inhabited, and are the dwellers within the earth good, or evil? There are two sets of `unorthodox` beliefs about the interior of our planet -- the theory that the earth may be `hollow` and possibly inhabited (by a race of giants?), and the second that a system of caverns exists beneath our feet that are controlled by both good and evil entities (thus the concept of a hell down below). This is a 189 page softcover book.
