This is a retold version of the story of Jacob and Esau, or, in this telling, Yankle and Esav, their bitter rivalry, and the conflict between Isaac and Rebecca, about who is the "favorite son."
It's a modern retelling, with cars and planes and a chain of restaurants named after Yankle, who is the true chef in this family. Yet in many ways it retains the setting of the Bible's original story, with the family being desert nomads, with herds to care for, and the constant concern over enough water, and, most bemusing for me, we're explicitly told that the Scriptures haven't been written yet, and that Yankle and Esav's story will be part of those scriptures. To me, this last bit seems a very strange choice.
