One night, under a full moon, four orphaned children set out on their own and turned an abandoned boxcar into their home. So begins the story of the Boxcar Children, a series of unforgettable, now classic favorites. Originally, Gertrude Chandler Warner wrote 19 stories about the Alden children. As the series grew in popularity after paperback publication, children wanted more books. Now there are many titles for children to enjoy. The paperback editions of The Boxcar Children Mysteries: #1, The Boxcar Children; #2, Surprise Island; #3, The Yellow House Mystery; and #4, Mystery Ranch are offered together in a cardboard case.
