From the author of Celestial Matters, which won the Compton Crook Award for best first novel and earned the author two nominations for the John W. Campbell Award for best new writer, All of an Instant is a large-scale, ground-breaking SF novel. It chronicles the discovery of a medium of existence outside of time (the Instant), from which one can influence all past and future history. War dominates this strange, abstract place — war among forces contending for control of all time and place.As Harry Turtledove said of Garfinkle's first novel, "This is hard science fiction with a difference. Garfinkle works out the implications inherent in them as rigorously as any writer has done....A fast-paced adventure plot with lively, well-differentiated characters."
