On the first day of seventh grade, Rex encounters a bump in the road—a big angry pimple right in the center of his forehead. And this is only the beginning of his problems. What follows is a frustrating battle with stubborn acne, body odor, and other embarrassments of puberty.

Seventh-grader Viv never looks forward to picture day. It’s just another day where she wears a boring braid and no one notices her. (Her two best friends, Milo and Al, don’t count, of course.) But enough is enough. This year, she’s taking matters into her own hands. Literally. Viv grabs a pair of scissors, her phone for live-streaming, and, well, bye-bye braid. Suddenly Viv is an over-night influencer at Brinkley Middle School. Everyone wants her help planning their next big moment—from haircuts, to dance proposals, activist rallies and mathlete championships. 

Five students meet in the school cafeteria when they're forced to complete their school community service hours. There's George: the brain. Sara: the loner. Dayara: the tough kid. Nico: the rich kid. And Miguel, the jock. They immediately know that they have nothing in common with each other... even though their school administration has decided that they all belong together.

Sixth grade isn't as great as Rex thought it would be. He's the only kid who hasn't had a growth spurt, and the bullies won't let him forget it. His closest friend is unreliable, at best. And there's a cute girl in his class who he can't stop thinking about. With so much going on, everything is a blur—including Rex's vision! So when he discovers that he needs glasses, and his family can only afford the ugliest pair in the store, any hope Rex had of fitting in goes completely out of focus.

Feng-Li can’t wait to discover America with her family! But after an action-packed vacation, her parents deliver shocking news: They are returning to Taiwan and leaving Feng-Li and her older siblings in California on their own. Suddenly, the three kids must fend for themselves in a strange new world—and get along. Starting a new school, learning a new language, and trying to make new friends while managing a household is hard enough, but Bro and Sis’s constant bickering makes everything worse.
