A Day No Pigs Would Die tells of Peck's childhood experiences, and the author models the main character after himself.

Soup also treats Peck's early life in rural Vermont, and Rob narrates the story, but Soup Vinson, his best friend, becomes the focus of the action. Lighthearted and delightful, Soup is one of a ten-book series that Peck will undoubtedly continue.

Peck also serves as the main character in his book of poetry, Bee Tree, and in his half-prose, half-poetry volume, My Vermont. Three of Peck's books, Soup and Me, Soup for President, and Mr. Little, have been made into Afterschool and Weekend Specials for ABC-TV.
