"Greg Heffley's on a losing streak. His best friend, Rowley Jefferson, has ditched him, and finding new friends in middle school is proving to be a tough task. To change his fortunes, Greg decides to take a leap of faith and turn his decisions over to chance. Will a roll of the dice turn things around, or is Greg's life destined to be just another hard-luck story?"--

"Dark times have fallen on McQuarrie Middle School. Dwight is back--and not a moment too soon--as Kellen, Sara, and the gang face a new Menace: the FunTime Educational Program. FunTime is supposed to raise students' standardized test scores. Instead, it's driving everyone crazy. The students turn to Origami Yoda for help"--

"It's a frenemy showdown and Nikki Maxwell has the worst luck. Of all the schools she could have been assigned to for the student exchange week program, she's stuck at North Hampton Hills, her arch nemesis MacKenzie Hollister's new school.

Rafe Khatchadorian's new year at middle school is starting to look depressingly like the old one, except that art class is going well--and when he joins the flag-football team and demonstrates some talent as a running-back, he discovers a way of dealing with his bullying nemesis and teammate, Miller the Killer.

"Steve has plans to take over his middle school, but when a nefarious villain beats him to the punch, Steve will have to consider doing the most horrific thing of them all: teaming up with good guy Vic Turry to save his school and maybe the entire town!"--

The Dunwiddle Magic School (fifth to eighth grade) is intended for children whose magic is "upside-down" like Dory (who turns into a combination of a kitten and dragon) and Pepper (whose uncontrollable "fiercing" terrifies everyone around her)--so the Show Off, where fifth grade students are supposed to showcase their skills, does not really seem like a good idea.
