Talented but painfully shy eighth-grader Lark secretly writes feisty, heartfelt songs about her life-about school, crushes on boys, not getting along with her mom, and missing her dad who lives in Nashville. But that secret becomes harder to keep when Lark's mother, a music record executive at her own label, announces that British boy band Abbey Road will be coming to live with them while they make their first album!
 
Sharing her L.A. house with three noisy, mischievous rising stars isn't as glamorous as expected, especially when things aren't going smoothly with the band members. When one of them plagiarizes one of Lark's songs and passes it off as his own, will Lark gain the courage to step into the spotlight herself?
