Mika, who likes things to be perfect, loves the pottery teacup from Japan her Obaachan gave her. The white and blue colors remind her of the clouds and the sea, and it feels cool and heavy in in her hands. When Mika accidentally breaks the cup, she’s devastated. Obaachan assures her it can be fixed, but after it’s repaired, “Golden lines zigged across the blue. Golden lines zagged across the white.” Obaachan explains that this kind of repair is called kintsugi—“to join together with gold.” Mika isn’t sure about it—the cup is no longer perfect after all—but she realizes it still reminds her of the beauty of the sea, this time during a lightning storm she once saw. More importantly, with Obaachan’s help, she realizes accidents happen, and that imperfect doesn’t mean useless or unworthy of love. Sophisticated ideas explored through a child-centered, accessible story in this picture book about a Japanese American child and her grandmother. Warm, colorful mixed-media illustrations accompany the story.
