A beach cleanup leads Henry, Jessie, Violet, and Benny on a new set of adventures. When an oil spill takes place off the coast of Connecticut, the Aldens are happy to volunteer to help clean up the animals affected, including a rare species of shore bird. But could more have been done to prevent the spill? As the Aldens take up the case, it leads them on an adventure to help other endangered animals around the world. Gertrude Chandler Warner grew up in Putnam, Connecticut. She wrote The Boxcar Children because she had always dreamed about what it would be like to live in a caboose or a freight car―just as the Aldens do. When readers asked for more adventures, Warner wrote more books―a total of nineteen in all. After her death, other authors have continued to write stories about Henry, Jessie, Violet, and Benny Alden, and today The Boxcar Children® series has more than one hundred books.
