Come to an end, all good things must. In this hilarious conclusion to the blockbuster series, Tom Angleberger uses his spot-on grasp of middle schoolers and pitch-perfect humor to pit the Rebel Alliance against their evilest, sourest villain yet! After successfully fighting to save the seventh-grade field trip in Princess Labelmaker to the Rescue!, Tommy and the gang prepare for a well-earned day of fun and adventure . . . but of course it won’t be that easy! This field trip will be full of shifting alliances and betrayals, carsickness and sugar highs. Trouble starts even before they leave school, when Principal Rabbski decrees the field trip an “origami-free zone.” Dwight secretly folds a Yoda from a Fruit Roll-Up, but will he be a match for the sour, hate-filled emperor of darkness that Harvey makes from a desiccated pickle?
