Georgia Khatchadorian plans to excel at Hills Village Middle School in all the places her troublemaking brother failed.

When the evil Mrs. Stricker threatens to send Junior, Rafe Khatchadorian's dog, back to the pound, Junior and Rafe go to obedience school to learn how to follow the rules.

Rafe and Jimmy are in charge of a celebration of books and reading, but when a small issue becomes a big problem that threatens to derail the event, they must work fast to keep things on track.

When Rafe is invited to attend an all-expenses paid art field trip in California, he jumps at the opportunity, but things go sideways, as they always do for Rafe, after he realizes he'll be participating in a "Cultural Campout" in the desert and a series of unfortunate events follow, including an encounter with a cranky crocodile, a claustrophobic trip into an ancient cave, and a plot to smuggle a legendary missing diamond.
