From the creator of A Book of Sleep and A Book of Babies comes a beautiful new book of animals—and opposites! The sky is dark and the Opposite Zoo is CLOSED. But the monkey's cage is OPEN! Time to explore. . . Follow the monkey as he visits all the animals in the zoo: fast and slow, big and small, noisy and quiet, soft and prickly! Filled with energetic illustrations, friendly animals, and a simple text, The Opposite Zoo is a fun and lively introduction to animals and opposites. Praise for Il Sung Na: “Il Sung Na’s illustrative art is so joyous, so jubilantly colorful, it feels celebratory and poetic even when the story is simple and spare.” —The Boston Globe (A Book of Babies) “[A] grand read-aloud.” —Kirkus Reviews, Starred (Welcome Home, Bear) "It’s the rare picture book that, upon arrival, feels as though it has been around for years already; Na’s belongs to this group.” —Publishers Weekly, Starred (A Book of Sleep) "Vibrant [and] whimsical.” —School Library Journal, Starred (Snow Rabbit, Spring Rabbit)
