"One of the most convincing depections of an alien society ever written." - Robert Silverberg & Martin H. Greenberg "We've read of mutant supermen, of strange and alien races on other worlds. But never have we had a tale of quite so homely, yet so utterly alien a race, nor of quite such a supermutant. Chandler has a yarn to tell." - Harry Harrison & Brian W. Aldiss "Arguably his finest work of science fiction." - Isaac Asimov
