The connection to rum running and Prohibition was fascinating. I also enjoyed Harmony's passion for hockey, and the fact that a teammate who gave her grief was reprimanded by his father and made to apologize was great. Readers who like books from animals' perspective will enjoy Queenie and Arthur's take on things, as well as their love for sausage. The Bowser and Birdie books do well in my library.
I wasn't a fan of Sheriff Hunziger, Bro, and Arthur all be depicted as not very bright. One character, maybe, but this made me suspect something bad in the water. Hunziger is just evil, but Bro sounds like he might need some intervention.
