If I were to rate this when I first read it years ago, I probably would give it four stars. Of all the Animal Ark books, this was my favorite. Mostly because the dog, Sasha, was a beagle and I love beagles (I have a dog and he is a beagle). I can't really remember the exact events in the book, but I think Mandy and James visit the SPCA and Sasha is injured. Anyway, it was pretty good. The whole series in general (or the books I read- I didn't read the whole series) is pretty good and I would recommend for kids ages 8-10.
