From the author of National Book Award finalist Hey, Kiddo.

Serving justice . . . and lunch!

Lunch Lady can sniff out something rotten like no one else—and there’s definitely something rotten going on in the library. The usually friendly librarians have become cold and secretive. Even Dee can’t seem to crack a smile out of them. What darkness may lurk in the hearts of librarians? Lunch Lady is on the case! And Hector, Terrence, and Dee are along for a wild ride!
