Strike of the Sweepers (Janitors)

The stakes have never been higher, and you've never seen squeegees do this before! 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 fabled Manualis Custodem in hand, Spencer must figure out how to summon the founding witches if they ever hope to mop up and save education.
