The constellation of Hydrus, known as the Serpent, is compact and obscure as seen from Earth's sky. Even in the great era of interstellar colonization it remained obscure. For ti was under strict quarantine - harboring an intelligent race, powerful, alien and inhuman.
Yet there were human colonies within the Serpent's Reach, cut off from the galaxy beyond, with their own inbred culture, their Families and traditions, and their special relationships to the inhuman majat.
This is the strange and brilliant novel of Raen, the last of the massacred Sul Family, and of her lifetime pledge to find vengeance. It was to take her across the worlds of the Reach into the very center of the alien webwork, into the strands of thought and counter-thought that knit the forbidden constellation into a complex of interbred cultures that no outsider could hope to unravel.
