有声读物: Heads of Cerberus

A pioneering work in the alternate worlds genre, The Heads of Cerberus was serialized in The Thrill Book in 1919 and published as a novel in 1952. A vial of grey dust transports three unwitting time travelers to a totalitarian version of Philadelphia in the year 2118. While certain landmarks stand unchanged, the societal structure is unrecognizable. Superlative adjectives and numbered buttons have replaced names and an oligarchy wield godlike power over the masses. To return home, the trio must win over the Loveliest, outsmart the Cleverest, and survive a deadly competition. - Summary by Christina Fu
