"Gopal captures the entire arc of a "sister day" right down to the snug nighttime rituals. The text pops and the digital illustrations use texture and color to keep up with the girls' energy as they -cycle through childhood's myriad -emotions... A celebration of sisterhood, of play, and problem-solving, all at once. A perfect purchase." --School Library Journal

"The colorful, cheery illustrations are full of playful moments that show the children using their imaginations...An ode to sisterly love and creative play." --Kirkus
