'Lost Island' (Story Code '47397') by Mel Goldberg Story by Lou Shaw

Searching the Pacific Ocean for a downed satellite, Steve saves a young woman named Da-nay from drowning, and then helps her escape from her two pursuers. A grateful Da-nay tells Steve that the satellite has crashed on her island, which is populated by the descendants of an alien race; although their island is protected by an impenetrable force field, which renders it invisible from a distance, Da-nay promises to lead Steve to the satellite if he will help her people. It seems that a man named Torg is leading a revolt on the island and threatening its inhabitants, who are unable to leave because they have no immunity against disease; Da-nay asks Steve to get hold of an immunity serum that is being developed in Hawaii, which would enable Da-nay and her people to obtain their freedom…
