É Phillip Jose Farmer, "Esboços Entre as Ruínas da Minha Mente"
A space ship arrives in our solar system and time starts going backwards. People wake up thinking its Wednesday but it is really Sunday and they had no memory of the last four days. The next day is worse as the same thing happens and they lose four more days. This goes on and on as grown people start drooling like babies and are unable to take care of themselves. How do the world governments deal with the problem and what are the long term affects on society?
