Cute, silly fun, with an escaped classroom pet story turning into a tale of superhero substitute teachers trying to save the world from evil classroom pets. I have some issues with the story- the MC, Milton, is responsible for the ferret escaping, as he forgot to latch the cage. While this was an accident, I did expect some sort of reprimand about responsibility, keeping the pet safe, all that stuff. The tech could've been more James Bond and less Get Smart, something more easily hidden than a communication helmet, especially as the helmet didn't play into the story. However, overall this was fun, and has some elements like end-of-chapter questions and encouragement, and end-of-story prompts to engage readers. Not a bad start to a series, not great, but not bad!
