Every city has a soul. Some are as ancient as myths, and others are as new and destructive as children. New York City? She's got five. But every city also has a dark side. A roiling, ancient evil stirs beneath the earth, threatening to destroy the city and her five protectors unless they can come together and stop it once and for all. The first book in a stunning new series by a Hugo award-winning and New York Times bestselling author.
