Time of Wonder is a 1957 children's picture book written and illustrated by Robert McCloskey that won the Caldecott Medal in 1958. The book tells the story of a family's summer on a Maine island overlooking Penobscot Bay, filled with bright images and simple alliteration. Rain, gulls, a foggy morning, the excitement of sailing, the quiet of the night, and the sudden terror of a hurricane are all expressed in this book. This was McCloskey's second Caldecott, the first being Make Way for Ducklings in 1942.
