In this all-new very special mini-series, the Aldens have been recruited by a secret society to return lost artifacts and treasures to their rightful locations―all 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 now, on the 75th anniversary of the first book, the Boxcar Children series has more than one hundred and fifty books.
