The capstone of the Roberta Kells Dorr biblical fiction series is a new work, one yet unpublished, an epic story of Abraham's descendants featuring Isaac's sons, Jacob and Esau, told with the same critical eye and careful study. From the moment when Abraham fears he has waited too long to find Isaac a wife, Dorr expertly follows the narrative and intertwining biblical stories of Abraham's family centered on the twin sons of Isaac. The story ends much like it began when Jacob blesses two of his sons, Manasseh and Ephraim, saying that the younger will become greater than the older, a theme that is seen throughout "The Sons of Isaac. "
