George is Emily's first friend, although imaginary. During the day, they play hide and seek and play ball with Emily's dog, Susie. At night and during nap, George joins Emily in her dreams and together they travel to faraway places to play with all types of baby animals. Yet with all this fun, George and Emily's favorite activity is reading. George can vividly describe to Emily places named in the storybooks as if he has personally visited each location.

That night, Emily has a dream about George hanging from her lampshade singing "Happy Birthday" to her. When Emily wakes, she finds her lost book of poems and knows in her heart George has visited once again.
