In the 25th century, only the Schindleria possess the secret of faster-than-light travel (FTL), thus exerting an economic stranglehold on all interstellar travel. For a century and a half, mankind has operated within their influence, till now there are at least a dozen human colony worlds scattered along Schindlerian trade routes.

Sonja Merrick, while serving as a military pilot, has witnessed atrocities for which this alien race is responsible. Now piloting a civilian cargo ship, she is currently ferrying an exploration team to a star system containing a derelict starship. From its wreckage, her passengers hope to salvage a functioning FTL drive of mysteriously non-Schindlerian origin. But the Schindleria are not yet ready to relinquish their monopoly of a technology they acquired through ancient genocide.
