No one takes Spencer Zumbro seriously when he tried to warn his classmates about the mysterious things prowling the halls and classrooms of Welcher Elementary School. But when he sees Marv, the janitor, going after one of the creatures with a vacuum, he knows he's not the only one who can see them. With the help of his new friend, Daisy, Spencer has to find out what the janitors know. The children's search uncovers the magic taking place behind the scenes of their seemingly ordinary school.
A secret society of janitors with wizard-like powers continue the battle. But now, the stakes are even higher. The Bureau of Educational Maintenance is after Alan Zumbro, and this time the evildoers mean business - deadly business. Spencer, Daisy, and their little team of Rebels must find the source of all magical Glop and destroy it before it can destroy the world as we know it.
"Best yet in the series "
Now more than ever, Spencer, Daisy, and even Dez must fight to save schools everywhere. Toxites, the small creatures that love to feed on the brain waves of students, are just the beginning of their troubles. The Bureau of Educational Maintenance (BEM) is after Spencer, and the Rebels hope to sneak him to safety within the walls of an elite private school. But danger follows Spencer and his friends, testing their loyalty and trust as well as their Toxite-fighting skills.
"Better than the first"
It is a wild and slightly unsanitary ride as Spencer, Daisy, and the rebels find themselves chased by Mr Clean's new and terrifying breed of toxite - the Sweepers. Time is short. With the fable Manualis Custodem in hand, Spencer must figure out how to summon the founding witches if they ever hope to mop up and save education.
