Kane was awesome as always, and the side characters - especially Sal and Rat - were beautifully rendered.
But Emelda lost something in this book, I felt. She became a Mean Girl. I didn't like her as much as I did in the other books. There were a lot of animal characters, but their behaviour logic felt under-researched and kept jolting me out of the story with things that didn't make sense (if you know animals!)
And I felt the villain was insubstantial. There, but flimsy and underdeveloped. Felt a bit... trite.
But the writing was good, I laughed, and it was entertaining as hell.
