Tedla is young, beautiful and blond but is neither he nor she. On a far-off world, an asexual class of blands exists to serve their fellow humans, protected and isolated from contact with the rest of the universe. But no bland has ever left its sheltered homeworld--until now. Tedla has been found in an alley light-years away from its planet. And it has just tried to commit suicide. Val, an expert in alien cultures, helps Tedla recuperate and in doing so, uncovers the secret tortured world of the blands.

Upon arrival, the team finds an extraordinary crystalline planet, laden with dark matter. A crew member is found murdered and Thora mysteriously disappears. Thought to be uninhabited, the planet is in truth home to a native blind populace, who navigate their world with a bizarre vocabulary and extrasensory perceptions.
