He's going across the ocean from the states to visit his Korean grandpa. When he and his mom get there, everything smells funny, he doesn't like the food, and there's nothing to do.
Abrams Young Readers sent me a copy of this book to read for review (thank you). It has beeen published and you can get a copy now.
When he's playing with his ball, it hits some of the pots of orchids. He sits down and cries waiting to be yelled at. But his grandpa realizes how bored he is and begins to play with him. Pretty soon he's having a great time.
When they leave, he's already counting on going to visit again next year!
