S.O.S.: Society of Substitutes #4: Super Fun World

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 fourth book of this hilarious, highly illustrated early chapter book series.

It's Spring Break! Milton Worthy and his family are off on a vacation to Super Fun World. It's a week filled with roller coasters, rides, and fried food--and no super-sub missions for seven whole days.

Everything is going according to plan until Milton gets stuck looking after Noah--part-time classroom pet, full-time evil mastermind--who has an entirely different kind of getaway in mind.

Will Milton be able to figure out Noah's latest plot for world domination before it ruins his family's fun time?
