Ben’s books include It Came in the Mail, the Tater Tales series and the New York Times bestselling Narwhal and Jelly series. Andy is the author and illustrator of the critically acclaimed picture book A Home Under the Stars and the co-creator of the interactive Science Explorers series with Amy Seto Forrester. Ben and Andy live in Seattle, Washington, a great place for cloud watching.
