A time projection of what future millenniums may bring. The atom ray suspended and surrounded city of Kronweld has more than Orwell's Anti-Sex League -- it has locked the secrete of life in its forbidden Temple of Birth. Ketan, the sceptic Seeker, and Elta his love, solve the enigma, see the city destroyed and go on to a hope of normal future life. For libraries, the situation here may be suspect, but the handling of it is not sensational.
