Plot introduction
The novel concerns people who, after inhaling a grey dust, are transported to a future totalitarian Philadelphia in 2118.

Reception
Groff Conklin called it "perhaps the first science fantasy to use the alternate time-track, or parallel worlds, idea." Boucher and McComas praised the novel as "a slightly dated but still originally imaginative and acutely satiric story." P. Schuyler Miller found Cerberus "dated and old-fashioned", but noted it was "a pioneering variation on the parallel worlds theme."

Everett F. Bleiler described the novel as "highly imaginative work, one of the classics of early pulp fantastic fiction", commenting that despite simplistic characterization, "the cynical anti-authoritarianism" in the description of the imagined future culture "is refreshing." Bleiler also noted that the novel's resolution "is a fine anticipation of the work of Philip K. Dick." Damon Knight wrote "Those who insist on the close reasoning and the satirical wit of modern science fiction will find surprising amounts of both here."
