While the 1991 Time’s Arrow is very much the best-known example of reverse chronology literature, the idea had been explored previously by Philip K. Dick’s 1967 Counter-Clock World. [Oct 2006]

“Dick’s best books always describe a future that is both entirely recognizable and utterly unimaginable.” –The New York Times Book Review

Counter-Clock World is a 1967 science fiction novel by author Phillip K.
