My kids loved this series when they were little, especially The Giggler Treatment. So when I heard there was a new one, I was curious. I was disappointed, however. Too much repetition (I know that's part of how Doyle tells the story, but it was maddening after a while) and not enough of the human characters. The reason the first book is the best is because of the interplay between the humans, the Gigglers, and Rover. This time it's almost all Rover and the story suffers because of that.
