"This poignant . . . narrative navigates complex themes of friendship, loneliness, kindness, and bravery. A deeply personal tale that underscores the power of kindness." — Kirkus Reviews

"Say offers a tender narrative about a youth who saves a baby sparrow from a group of village bullies. Softly colored pen, ink, and watercolor vignettes give delight to the brief relationship between child and sparrow." — Publishers Weekly

"The narrative gently relates the progression of [Kozo and the boy's] mutually rewarding relationship and the meaningfulness of care and kindness, themes furthered in Say's soft, realistic, and expressive watercolor illustrations. Say’s endnote provides story background and context, including about growing up in post-WWII Japan and the real-life Kozo."
— Booklist

"Say’s pen, ink, and watercolor illustrations depict with equal clarity both the rural Japanese setting and the young protagonist’s quiet determination and devotion. An author’s note closes the affecting book." — Horn Book Magazine
