A heartfelt novel about a neurodivergent girl that challenges us to reexamine what makes someone "gifted," perfect for fans of Fish in a Tree and Frindle.

Ruby Emmerson has always felt like the "dumb" twin. Struggling with dyslexia, dysgraphia, and dyscalculia, she feels out of place at her competitive charter school, especially as her twin brother Bryce excels both academically and socially. When she fails a math test despite getting extra help, she fears she'll flunk out of Benton Academy and drag her brother back to their old school.

In a moment of frustration, Ruby vents anonymously online, describing herself as an imposter-a mango among lovebirds. But to her surprise, she's far from alone.

As her account gains a following, tensions rise with her brother and her posts draw the unwanted attention of the school administration. Now, Ruby must find the courage to challenge Benton's high-pressure environment and advocate for herself and all the other "Mangoes" out there.
