A hardcover first UK edition, Abelard, of a collection of short fiction by Robert Siverberg,
Light edgewear to the covers, otherwise unmarked.
A Native American, on a mission to prepare a new planet for colonization, becomes disturbed by the concept that the native life he's exterminating might be sentient. the far future protagonist, Tom Two Ribbons, finds himself on an alien planet whose odd native indigenous species will be in the way of the soon to arrive human colonists.
Two Ribbons anxiety about this planet sized irony unfolds into a deep spiritual and personal struggle. The question is asked, are the natives intelligent? And if so, is this genocide? Is humanity once again destroying a culture in the name of progress?
