The first day of middle school means trading in freeze tag at the pool for new schedules, fabulous outfits, and a fresh start. But for 11-year-old Kaylan, the chaos of new locker combinations, cafeteria cliques, and potential first kisses is more than she can handle. She dreads the start of sixth grade and feels like she wants - no, needs - a winning game plan. Luckily, Kaylan and her effortlessly chill BFF, Arianna, have a fool-proof plan for tackling transitions: a list of 11 things they need to do to totally transform themselves before they both turn 12 in November. 

Eleni is the kind of person who’s always had a BFF—an automatic, guaranteed by-her-side person—at home, at school, and at camp. And since before she was even born, her very best friend has been Sylvie Bank. But when Sylvie’s end-of-summer birthday party becomes the end of their friendship, Eleni can’t picture starting middle school without her BFF by her side. She can’t picture anything without her BFF—especially the looming school overnight. Who will she even room with?

Gracie has never felt like this before. One day, she suddenly can't breathe, can't walk, can't anything - and the reason is standing right there in front of her, all tall and weirdly good-looking: A. J. But it turns out A. J. likes not Gracie but Gracie's beautiful best friend, Sienna. Obviously Gracie is happy for Sienna. Super happy! She helps Sienna compose the best texts, responding to A. J.'s surprisingly funny and appealing texts, just as if she were Sienna. Because Gracie is fine. Always! She's had lots of practice being the sidekick, second best.

The prettiest: It’s the last thing Eve Hoffmann expected to be, the only thing Sophie Kane wants to be, and something Nessa Flores-Brady knows she’ll never be...until a list appears online, ranking the top 50 prettiest girls in the eighth grade. It’s time for a takedown. As the three girls band together, they begin to stand up not just for themselves, but for one another, too.

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.
