Little readers will enjoy thinking about big questions in this bright and colorful picture book that explores time and the meaning of tomorrow.

Owl is confused. She doesn't know what tomorrow means. When does today turn into tomorrow? Does tomorrow begin in the middle of the night, at a certain time in the morning or not until you wake up? Mouse, Hedgehog and Rabbit try to explain, but Owl still doesn't understand. The forest animals make a plan to stay awake all night to find out, but what if they fall asleep? How can you tell it's tomorrow if it's already today when you get there?
