A bet about wardrobes between the wealthy Massie and middle-class Claire results in a testing of old friendships, a forging of new ones, and a change for the student body at Octavian Country Day School.

Following Christmas break, the girls are back together, but everything seems different with the addition of Alicia's cousin from Spain who is spending the semester at Octavian Country Day School.

Just as the Pretty Committee is getting bored with being expelled and Massie begins worrying about losing her spot as the most popular girl, Claire is cast in a Hollywood film, and as Massie and Alicia report live from the set, Kristen and Dylan keep them posted on events in Westchester County.

Massie Block: Stands at the threshold of the most ah-mazing secret room at OCD. But to prove the Pretty Committee is worthy of the honor, the girls need dates to Skye Hamilton's "famous couples" costume party. On top of all that, Massie has to convince her old crush, Chris Abeley, to be Skye's date . . . or else they can kiss the room-and their popularity-goodbye. How will she ever get her girls suitable dates and melt Chris's heart? She'd need to...

When the Pretty Committee deems its boy-fast null and void, boy fever sweeps through BOCD. What better way to back handspring into new crush Dempsey's heart than cheer for him on the soccer field? And just like that, Massie forms BOCD's first cheerleading squad.

Now that the Pretty Committee is no longer boycotting boys, the eighth-grade friends cannot decide who has a crush on whom, putting the Clique in jeopardy again.

As the girls face some tough decisions and some life-changing events, the Pretty Committee may come to an end.
