Arguably the best time travel tale dealing with the Holocaust ever written, in our humble opinion.  A rebellious group of time travelers attempt to prevent one of the greatest atrocities humanity ever devised: Auschwitz. Monitor and ace enforcement operative Gaspar James is sent to stop them.  Gaspar knows that the horror must be allowed to run its course in order to preserve the integrity of the time line. At least that's what he has told himself throughout his service to the Moiety, the group charged with overseeing the continuity of time. But even Gaspar has his doubts—and millions of lives hang in the balance.
