Idaho has never seen anything like the green-haired, green-eyed cutie from the planet Kanab, found one May morning by junior park ranger Tom Breedlove in a verdant corner of Selkirk Wilderness Area clad in a transparent gown of ""laminated hydrogen plasma."" The Pentagon and the State Department have never heard anything like her request for a spoonful of uranium-235 to send her stranded ship onward in its search for a new home to replace nova-blasted Kanab. Isn't it a bit odd that the Kanabians have to be off the planet before the summer solstice or be captured forever by the biological lure of Earth's sun? And why is the entire ship's crew female, except for one young boy obviously there under duress? Just what is the Kanabian mating system? Can this book really be as awful as it sounds? Yes, indeed. Boyd (author of the malodorous Barnard's Planet, 1975) writes with somewhat less poise and control than a busted cement mixer.
