I have really enjoyed the Sigma Force series for a long time, but this 13th edition was not a lucky read for me. I felt like Rollins spent way to much time on the inner lives of his animal protagonists. This is understandable, given that he is a veterinarian in real life, but still a little goes a long way. Between that and the truly silly complete lucky fluke that leads to the final rescue, this book's story line was the weakest in the series. Even so, I enjoy the characters and it was a good fun quick read, so worth taking in if you are into the series yourselves.
