Boom-Boom-Boom. My papa loves me." It's deep winter in the Antarctic and a little penguin baby waits in the cold and snow for its mama to return from her long journey to find food. But all the while, the baby is protected and kept warm by its papa, until Mama returns with food . . . and love. With stunning illustrations and a spare but powerful story, Gianna Marino captures the icy beauty of Antarctica and the wonders of a penguin family that thrives there.
