<DIV>On the island of Ponape in the South Pacific, the cold light of a full moon washes over the crumbling ruins of an ancient, vanished civilization. Unleashed from the depths is the Dweller, a glittering, enigmatic force of monstrous terror and radiant beauty that stalks the South Pacific, claiming all in its path. An international expedition led by American Walter Goodwin races to save those who have fallen victim to the Dweller. The dark mystery behind the malevolent force is Muria, a forgotten, mythic world deep within the earth that is home to a legendary people intent on reclaiming what was theirs long ago. This commemorative edition of <I>The Moon Pool</I> features an introduction by Robert Silverberg, a review of the first edition, and a glossary of the Murian language.</DIV>
