In the mid-1970s Sunny Lewin is back, star of her personal show, facing the prospect of Middle School, and dealing with the problems of her somewhat dysfunctional family--in particular her older brother, Dale, who has been sent off to a military academy because of his delinquent behavior.

After finally getting a cell phone, Babymouse tries to increase her popularity in middle school by becoming the queen of social media.

"Babymouse tries out for the middle school play, but instead of landing the lead role, she gets stuck with playing a clown with one line of dialogue"--

Eighth grade turns out to be an eventful year for Ginny and her family, as notes, lists, report cards, doctor bills, and other "stuff" reveal that the family moves to a big new house, Brian starts to be more than just a friend, Ginny's mother has a baby, and her stepfather loses his job.
