The Overman Culture - Novel 1971
Michael was quite young when he discovered that some of his playmates bled if they cut themselves, and some didn't. For a long time he didn't think about it. Nor did it seem strange to see Zeppelins being attacked by jet fighters above London's force field, or glimpse Queen Victoria walking with Winston Churchill in the Mall. Not at first.
But later he thought about these things - he couldn't help it. The world was real, and yet unreal. It was all desperately worrying. So Michael and his friends formed a society to investigate the world around them.
Despite the terrible things they discovered, things that made some of them insane, they never actually guessed the truth about the Overman culture. Until Mr Shakespeare told them.
