Surprise Island — Gertrude Chandler Warner

One warm night four children stood in front of a bakery. No one knew them. No one knew where they had come from.

Henry, Jessie, Violet and Benny used to live alone in a boxcar. Now they have a home with their grandfather and are spending the summer on their own private island.

There's a mysterious stranger on the island who must keep his identity a secret. And that's not the only surprise in store for the Boxcar Children on Surprise Island!
