Day of Timestop [EPUB ebook] 

Operation Timestop: 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.
