"Siblings Henry, Jessie, Violet, and Benny used to live in a boxcar. Now they have adventures everywhere they go. What secrets will the children find on their very own island?"--

Four orphaned children run away and live in a boxcar, until they are found by their grandfather. Includes a biography and photographs of the author.

After solving riddles from the secretive Reddimus Society to figure out their destination, the four Alden siblings fly to China, where they deliver an artifact at the Great Wall, but when they are next rushed to an elephant sanctuary in Thailand, the Aldens suspect they have been tricked and take extra precautions against their enemies.

The Alden children suspect that the other guests are somehow involved when things begin to disappear at the bed and breakfast where they are staying in Washington, D.C.

"On a rafting trip in the Pacific Northwest, the Aldens come across the story of a mysterious man who disappeared into the wilderness many years ago. Can you help the Aldens find out where the man went -- and what happened to the treasure he took with him? In this interactive, choose-your-path mystery, readers will make decisions that will help the Boxcar Children crack the case during their white-water adventure." -- Provided by publisher.
