"Sunfall" is a collection of stories set in the far future on an ancient Earth under a dying Sun that is emitting dangerous levels of radiation. Each story deals with a city and how it has evolved to cope with the fading Sun. Paris and New York City have become single self-contained structures with no "outside". In "The Only Death in the City (Paris)" this closed biosphere has resulted in no "new births": everyone who dies is reincarnated again in the city with all the memories of their previous lives. In "Nightgame (Rome)" the nobles while away their boredom by dreaming dreams captured from less fortunates using an apparatus no one knows the origin of.
