From Texas to Gothenburg is a far reach, but teen agers Tony and Helen soon slip into a new way of life. There's a good picture of family life, of school, of the daily round. And there are holidays spent in all parts of Sweden, so that the children get a sense of a whole country and not just the tourist spots. Rather unusual in a travel book, Stockholm, goal of many travelers, comes at the end, and bits of what they have seen and learned elsewhere, what they have come to know about rural and village and industrial and frontier Sweden comes into focus. The reader gets the feel of a people and a land.
