The Complete Paratime

From H. Beam Piper, the creator of the Terrohuman Future History and the bestselling Fuzzy novels, come the parallel worlds of Paratime--collected for the first time in one volume.

Infinite worlds allowed for infinite evil--unless the doorway to those worlds was most carefully guarded. The Paratime Police are an elite force of men and women charged with defending a million unsuspecting Earths from their more developed--and more ruthless--neighbors in parallel continua. From the original Paratime, which introduced the unceasing struggles of the time-traveling heroes, to Lord Kalvan of Otherwhen, the last Paratime story of a state trooper's conquest of an alternate Earth...The Complete Paratime is a grand science fiction experience.
