The concept was interesting, and the story held me enough to see the book through, but I never really felt like the main character was in any real danger, despite apparently being in life threatening situations a number of times. I also had trouble accepting how intelligent the Fuzzies actually were, despite apparently not having left some kind of mark on their planet, such as a town. 
 Overall, I am glad I read (listened, actually) this book, but I would have liked more to have been done with the idea.
