FAMILIES ARE DIFFERENT

In her first children's book, Pellegrini takes on the voice of her younger adopted daughter, Nico, who explains that she and her sister come from Korea; they don't look like their parents- -''I grew in someone else's belly, but my mom and dad are the ones who promised to love and take care of me forever.'' Comparing her family to others she knows, Nico discovers nine other patterns—varied in size, color, composition, and family resemblances—all ``glued together with...love.'' Like real people, the ones in Pellegrini's serviceable illustrations are a little homely, but they effectively communicate their mutual affection. Warm, attractive, and useful. (Picture book. 3-8)
