Janitors, Book 5: Heroes of the Dustbin (Unabridged‪)‬

Spencer knew that from the moment the Founding Witches had returned, the Rebel Janitors had begun disappearing. So many schools were defenseless now, the students' minds rotting from Toxite breath while the janitors vanished without a trace. Then it became personal. 

Although their enemies are powerful, their allies few, Spencer and his ream of Rebels are not giving up! But what chance do a handful of kids and one rescued janitor have against the combined evil of the Founding Witches and the Sweepers? Can the Rebels close the source of all Glop and stop the Toxites once and for all - or is the world doomed to fall under the control of the sinister Bureau of Educational Maintenance? 

This explosive series finale is a griping ride through conflicted loyalties and daring escapes, unexpected alliances and betrayals, and an ending you'll never forget!
