For more than 50 years, Herman Wouk has dreamed of writing a novel about the life of Moses Finally, at the age of 96, he has found an ingeniously witty way to tell the tale of The Lawgiver, a romantic and suspenseful epistolary novel about a group of people trying to make a movie about Moses in the present day.

At its centre is Margo Solovei, a brilliant young writer-director who has rejected her father's strict Jewish upbringing to pursue a career in the arts. When an Australian multi-billionaire promises to finance a movie about Moses, Margo does everything she can to land the job, including a reunion with her estranged first love, an influential lawyer with whom she has unfinished business.
