Lucy & Tom: From A to Z is an alphabet book featuring the classic children's characters Lucy and Tom, created by the celebrated author-illustrator Shirley Hughes. The book uses the simple, relatable daily activities and adventures of the two siblings to illustrate each letter of the alphabet. For instance, 'A' might be for apple or an adventure, and 'Z' for zipper or the zoo. The book serves as a charming educational tool, using the comforting, beautifully observed details of Lucy and Tom's ordinary childhood world to introduce letters and words.
