Realm of the Black Sun

On a near-suicidal mission to rescue the Dali Lama behind the Bamboo Curtain, CIA agent Stuart Mackenzie discovers beneath the ancient cellars of the Portala Palace an opening into another dimension, The Land of Shamballah, a realm inhabited by an ancient evil, imprisoned by the Buddhist monks.

But the secular Communist authorities are destroying the ancient bonds holding it back.

Mackenzie discovers the link between UFOs and an ancient evil that yearns to feed upon our unsuspecting world. He must discover how a modern man can thwart a spiritual threat that proves immune to the latest technological weapons. Along the way he frees Hilda, a young woman separated from the Nazi expedition to Tibet in 1938.
