The Suitcase

From the author of Friends comes a tender picture book about a boy who gets a new perspective on his grandparents after uncovering an attic of treasures and a suitcase of mysterious photos while staying with them for the summer.

When a boy goes to visit his grandparents in the summer, it isn't long before he gets bored. Every day is the same, and there's nothing to do except reading and gardening like his grandparents, which the boy thinks is dull and not fun at all. Then he goes exploring and finds a suitcase in the attic filled with incredible things, including pictures that show a young couple exploring the world, having fun adventures, and dancing and singing.

Who could they be?
