One of these “sons of thunder” offers a future she longs for, the other—the past she lost. From the sultry Chicago jazz clubs of the roaring twenties to the World War II battlefields of Europe to a final showdown in a Greek island village, they’ll discover betrayal, sacrifice and finally redemption. Most of all, when Sophie is forced to make her choice, she’ll learn that God honors the promises made by the Sons of Thunder.
