Wecker’s debut novel is set in New York City, 1899. She spins a yarn about a golem, a clay creature brought to life by a Hebrew mystic, and a jinni, a creature made of fire. Both supernatural creatures find themselves hiding among poor immigrants in turn-of-the-century New York, an ambience rendered affectionately by Wecker. The novel unspools like a fable, gradually accumulating moral force as Wecker’s plot threads gather together in a complex design.
