Two complete novels of courageous men and women struggling to survive in worlds of unknown dangers and implacable enemies: Sea Siege - The nuclear war had come at last and the research team on an island in the West Indies thought they had been lucky to survive. But survival was going to require more than luck, when they found themselves under attack by sea creatures out of darkest legend, directed by a previously unknown intelligence from the depths of the sea which was determined to eliminate mankind as a competitor and seize what was left of the world for itself. Star Gate-Long ago, the Star Lords had come from a dying Earth and settled on the Earth like planet Gorth where they found a primitive society and helped the inhabitants to rise to civilization. But now the native folk of Gorth have grown resentful and jealous of the Star Lords, who have refused to share their secrets of immortality and their powerful weapons-technology which led to the loss of Earth.
