Lancer Books, 1968. Mass market paperback. An early Farmer novel, said to be a sequel to "The Lovers" but bore little relation to the earlier story. Post-holocaust Paris is a pretty seedy stand-in for the original, but what can you expect when the goverment's main function is Orgasm Prevention & when the national hero is wandering around in Nowhen. But things are changing! Rumor has it that the Timetraveler is coming back in a few months. At which point, Time itself will come to an end. Also published as "A Woman A Day" and "Timestop!"
This book is part of the Philip José Farmer Standalone Novels series.
