As a child, I read and enjoyed the first in this series, The Shy Stegosaurus of Cricket Creek, but I did not find this sequek until I was an adult. It is set in a Native American reservation and the hero is a Naïve boy who is staying with his grandfather, an old shaman, when he meets the stegosaurus. It might be debated whether this is fantasy or SF, but I say a surviving stegosaurus might be real and therefore sf, but it would not talk fluent English, so I rate this as fantasy. ( )
