“I really enjoyed this story. As the summary says, "two creatures have wandered the Earth for generations. The aliens have no knowledge of each other...One, the changeling, has survived by adaptation, taking the shapes of many different organisms. The other, the chameleon, has survived solely by destroying anything or anyone that threatens it." I thought the development of the aliens was great - the changeling develops an empathy toward the humans it encounters and sometimes becomes; the chameleon develops into a malevolent being whose favorite human is Josef Mengele.
There are some areas where the book appeared too farfetched - especially the response of one of the main characters to discovering the existence of an alien - but overall the story held my interest and was actually quite a study in human behavior and rituals.”
