This book is immensely clever!  Toby has moved the city.  He didn’t want to, but he had no choice.  The thing he hates the most is that he can not see the stars.  And one night when he can not sleep a lion comes to his room asking for help finding the north star.  They explore the city and pick up other animals along the way.  This is where cleverness comes in.  It dawned on me half way through that they were picking up the animals from the zodiac and helping them find their way back home.  It was so well done.  Kudos to the illustrator for all the easter eggs that I originally missed like Toby’s shadow being a dragon.  This book was excellent!  I hope it makes the official rounds for the Caldecott.
