What happens when your BFF becomes your EFF . . . EX-Friend-Forever? When seventh-grader Mango Delight Fuller accidentally breaks her BFF Brooklyn's new cell phone, her life falls apart. She loses her friends and her spot on the track team, and even costs her father his job as a chef. But Brooklyn's planned revenge--sneakily signing up Mango to audition for the school musical--backfires when Mango not only wins the lead role, but becomes a YouTube sensation and attracts the attention of the school's queen bee, Hailey Jo. Hailey Jo is from a VERY wealthy family, and expects everyone to do her bidding. Soon Mango finds herself forced to make tough choices about the kind of friend she wants to have . . . and, just as important, the kind of friend she wants to be.
