One warm summer night, a frog jumps into Lucy's room with a magic party hat and an invitation for her to a birthday party. Lucy puts the hat on and -- when a moonbeam touches the hat out in the garden -- Lucy becomes as small as a leaf. So begins her wonderful adventure.

A taxi driven by Baby Bird, who is afraid to fly, picks up Lucy to take her to the party. Along the way, they stop for Madame Mouse, an inchworm hungry for birthday cake, and a tattered old doll who longs for his original owner who lost him years before. But suddenly, a huge owl blocks their path. He wants to eat them all for supper! Will they escape? Will they get to the party? Will the doll ever be reunited with his beloved owner?

In a lovely, lyrical text, the story unfolds to its happy ending. The magical pictures, painted with intricate detail and subtle colors, bring the moonlit garden to life. This is an extraordinary book of great beauty and vivid imagination that small children -- and adults -- will look at again and again, discovering new wonders and surprises as they look.
