From the back cover:
Hidden Rainbow is not an imaginary story, nor one dub out of antiquity. It is an actual story about real people, the Olesh family of a solid Catholic community in Yugoslavia, and their encounter with the New Testament in the early twentieth century. Through the eyes of John and Anna Olesh the reader is taken into the intimate life of a Yugoslavian village. John is severely censured for seeking economic opportunity in America as he leaves his family behind. Upon his return the family is visited by an evangelical missionary for which they are also censured. Though they are forbidden to communicate with the missionary, they cannot forget his radiant personality and his message. While John is away from home Anna fearfully accepts a "forbidden" New Testament. The reader shares in the consequences and feels the deep loyalties of tradition hanging in the balance, and shares finally in the doubts and triumphs as John and Anna find the power of God.
