Chava is a golem, a woman made of clay, who can hear the thoughts and longings of those around her and feels compelled by her nature to help them. Ahmad is a jinni, a restless creature of fire, once free to roam the desert but now imprisoned in the shape of a man. Fearing they'll be exposed as monsters, these magical beings hide their true selves and try to pass as human--just two more immigrants in the bustling world of 1900s Manhattan. Brought together under calamitous circumstances, their lives are now entwined--but they're not yet certain of what they mean to each other. Both Chava and Ahmad have changed the lives of the people around them. Park Avenue heiress Sophia Winston, whose brief encounter with Ahmad left her with a strange illness that makes her shiver with cold, travels to the Middle East to seek a cure. There she meets Dima, a tempestuous female jinni who's been banished from her tribe. Back in New York, in a tenement on the Lower East Side, a little girl named Kreindel helps her rabbi father build a golem they name Yossele--not knowing that she's about to be sent to an orphanage uptown, where the hulking Yossele will become her only friend and protector.
