If there's a problem in school, there's no substitute for the world-saving substitute teachers of the S.O.S.! This is the first book of this hilarious, highly illustrated early chapter book series.**

When Milton Worthy learns his classroom's pet ferret is the evil mastermind behind a dastardly plot for world domination, it's more than just about any kid could handle. But then not every kid is the son of a member of the super-secret, super-awesome Society of Substitutes!

Now it's up to Milton and his substitute teacher mom to save Beacher Elementary School before time runs out.
