Review this title!

What's the story?

All the world’s asleep -- except for the owl, who quietly watches different ways animals sleep on land and in the sea.

Is it any good?


This comforting book makes sleep time a beautiful curiosity rather than something to dread or fear. Il Sung Na’s bright-eyed owl watches over the snoozing world and shows how sleep is both universal and individual. He shows us whales sleeping as they move through the ocean, birds sleeping with one eye open, and a fish sleeping with both eyes wide open.

Na's illustrations make this a book to treasure. Kids will delight in the big-eyed birds and fish, and the delicate patterns playing across the animals and the night sky steep the simple story with magic and suggest sweet dreams abound. Absolutely beautiful, with a classic look and feel. Big-eyed birds and fish and the delicate patterns playing across the animals and the night sky steep the simple story with magic and suggest sweet dreams abound.

Families can talk about...

  • Families can talk about the different ways animals sleep. Which ones surprised you? How do you go to sleep?

  • The owl is awake at night and sleeps during the day. Can you think of other animals that are nocturnal?
