In Lost In Yonkers their father Eddie asks the characters Jay and Arty to move in with Grandma. They are not physically lost, they are emotionally lost because they are in a strange new place, and at first they do not understand Grandma. Grandma has many rules. She makes the boys watch the candy store, and charges them when people steal things. They think this is unfair. Grandma makes the boys eat a nasty mustard soup when they are sick. The boys are not allowed to bring any of their sports things into the house, or listen to the radio. All of these things force the boys to live very differently than they did before moving into Grandma’s house in Yonkers.
