On a donkey named Moise, Yonah begins a meandering journey, a young fugitive zigzagging across the vastness of Spain. Toiling at manual labor, he desperately tries to cling to his memories of a vanished culture. As a lonely shepherd on a mountaintop he hurls snatches of almost forgotten Hebrew at the stars, as an apprentice armorer he learns to fight like a Christian knight. Finally, as a man living in a time and land where danger from the Inquisition is everywhere, he deals with the questions that mark his past. How he discovers the answers, how he finds his way to a singular and strong Marrano woman, how he achieves a life with the outer persona of a respected Old Christian physician and the inner life of a secret Jew.
