From Jarrett J. Krosoczka comes Never Say Narwhal, the final installment in the hilarious, high-action middle grade series featuring two platypus detectives, perfect for fans of Diary of a Wimpy Kid, Big Nate, and Jarrett's own Lunch Lady series.

Frank Pandini, Jr. is the mayor of Kalamazoo City, and everyone is celebrating - everyone except for Zengo, O'Malley, and Cooper, who can't seem to close a single case. To make matters worse, a mysterious hulking shadow has appeared in waters around KC. Could this spell the end for the Platypus Police Squad?
