Now that Snip the cat is gone (but hardly forgotten), the classroom animals of the Midnight Academy are ready for things to get back to normal at the McKenna School. After all, protecting nutters (students) and lankies (teachers) is an around-the-clock job! When a rare coin and a strange code are uncovered in the school, Malcolm and the academy have another mystery on their hands.
To find answers, Malcolm must venture into the dangerous outside world full of shady characters, new friends, and old enemies. Once again, there are more secrets in the halls of McKenna than there are crumbs in Malcolm's Comf-E-Cube. Will Malcolm save the school and solve the mystery before it's too late? As the clock strikes 12, rejoin the animals of the Midnight Academy as they take on their most challenging assignment yet.
