The most hilarious, charming, realistic story of middle-grade friendships you''ll ever read, from Megan McCafferty, the mega bestselling, beloved author of Sloppy Firsts.

Twelve-year-old Ella has everything she needs to take seventh grade by storm, from the perfect outfit to the perfect new best friend.

She''s still not 100% sure why cool, confident Morgan has chosen Ella to be her newest sidekick, but Ella is flattered by the attention, even if it means giving up some of the things she''s always loved, like fantasy novels . . . and her former best friend, Sophie. Ella feels a little guilty about ditching Sophie, but middle school is no laughing matter, and Ella knows that it''ll be safer in popular Morgan''s shadow than by Sophie''s side.But life as Morgan''s best friend is trickier than Ella imagined.

Everything has to be perfect, from their "on brand" selfies to the videos they record of them singing. And the more demanding Morgan becomes, the more Ella starts to wonder if she made the right choice. But Sophie already has a new best friend, leaving Ella feeling more alone and out of place than ever.So when Ella discovers a new activity that she''s really good at -- a hopelessly dorky sport that Morgan has forbidden her from pursuing, Ella has to ask herself what matters more: popularity .

. . or staying true to herself? But does she even know who she really is without loyal Sophie by her side?
