The Mystery in the Cave

The Boxcar Children are visiting Dragon Mouth's Cavern. Their plan is to explore the area and go rock hunting. But when Benny finds a way into secret underground caves, the children have even more to explore. The problem is, it seems like someone doesn't want them there. Can the Aldens solve this underground mystery?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.
