Old Sci Short Story A friend of mine was telling me about an old sci book they read. It was a short story. They think it was about 100 pages or so. From somewhere maybe between 1950 to 1980. Maybe earlier than the 50s. It features aliens visiting earth. They are all blue females and each ship visits a major area of the world, US, China, Middle East, etc. In this book they see a woman in the US President's office wearing a cross necklace. They seem to share the same religion but they don't call it Christianity its something else they call it. They then decide to tell the President that they would like to speak to the human race and they had a meeting with members of the United Nations. The Alien visitors told humanity how they were once like humanity until an alien invasion came to their world and they had to fight back. The war cost them dearly with nearly all the males dead/wiped out and the females had to take up the reigns. What little males exist are a precious commodity to them.…
