Molly Frost is fed up.... Because Olivia was yelled at for wearing a tank top. Because Liza got dress coded and Molly didn't, even though they were wearing the exact same outfit. Because when Jessica was pulled over by the principal and missed a math quiz, her teacher gave her an F. Because it's impossible to find shorts that are longer than her fingertips. Because girls' bodies are not a distraction. Because middle school is hard enough.

When Mary Kate Murphy joins a special science pilot program focused on climate change, the class opens her eyes to lots of things she never noticed before about her small suburban town: Kids waste tons of food at school without a second thought. Parents leave their cars running in the pick-up lane all the time. People buy lots of clothes they don’t really need. Some of her friends who live in the city and are bused to her school don’t always feel included. And the mayor isn’t willing to listen to new ideas for fixing it all.

Quiet outsider Tillie is known around school for using her camera to find lost things, but when a boy named Jake needs help finding his dad, Tillie faces her biggest challenge yet. Ever since Tillie Green's car accident left her with a severe limp, she's kept herself hidden behind her camera. Through the lens, she watches her family and classmates, spotting the small details and secret glances that tell a much bigger story than what people usually see. Students call her "Lost and Found", because her camera knows when you last had your headphones.  

Eleanor Dross knows a thing or two about the end of the world, thanks to a survivalist grandfather who stockpiles freeze-dried food and supplies - just in case. So when she reads about a Harvard scientist's prediction that an asteroid will strike Earth in April, Eleanor knows her family will be prepared. Her classmates? They're on their own! Eleanor has just one friend she wants to keep safe: Mack. They've been best friends since kindergarten, even though he's more of a smiley emoji and she's more of an eye-roll emoji.

Felix Rannells and Benji Porter were never supposed to be field-trip partners. Felix is a rule follower. Benji is a rule bender. They're not friends. And they don't have anything to talk about. Until...they find a wallet. A wallet that belongs to tech billionaire Laura Friendly. They're totally going to return it - but not before Benji "borrows" 20 dollars to buy hot dogs. Because 20 dollars is like a penny to a billionaire, right?

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. 

As one of the only Asian American kids in her small Texas town, Christina just wants to fit in. Luckily, her best friend, Megan, who is Iranian American, can totally relate. The two girls have always been inseparable and relish creating elaborate fantasy worlds together. But middle school is a reality-check, and suddenly popularity is way more important than playing pretend. When cheerleading tryouts are announced, Christina and Megan literally jump at the chance to join the squad. But does fitting in actually equal belonging?

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.

Melody is not like most people. She cannot walk or talk, but she has a photographic memory; she can remember every detail of everything she has ever experienced. She is smarter than most of the adults who try to diagnose her and smarter than her classmates in her integrated classroom - the very same classmates who dismiss her as mentally challenged because she cannot tell them otherwise. But Melody refuses to be defined by cerebral palsy.

Jen did not want to leave the city. She did not want to move to a farm with her mom and her mom's new boyfriend, Walter. She did not want to leave her friends and her dad. Most of all, Jen did not want to get new "sisters", Andy and Reese. As if learning new chores on Peapod Farm wasn't hard enough, having to deal with perfect-at-everything Andy might be the last straw for Jen. Besides cleaning the chicken coop, trying to keep up with the customers at the local farmers' market, and missing her old life, Jen has to deal with her own insecurities about this new family.
