Between homework, studying, and Chinese school, Mĕi Yīng's summer is shaping up to be a boring one. Her only bright spots are practice with her soccer team, the Divas, and the time spent with her ni nai, who is visiting from Taiwan. Although Mĕi Yīng's Mandarin isn't the best and Ni Nai doesn't speak English, they find other ways to connect, like cooking guōtiē together and doing tai chi in the mornings. By the end of the summer, Mĕi Yīng is sad to see Ni Nai go but excited to start fifth grade. Until new kid Sid starts making her the butt of racist jokes. Her best friend, Kirra, says to ignore him, but does everyone else's silence about the harassment mean they're also ignoring Sid . . . or her? As Sid's bullying fuels Mĕi Yīng's feelings of invisibility, she must learn to reclaim her identity and her voice.
