"Five New Yorkers must come together in order to save their city from destruction in the first book of a stunning new series by Hugo award-winning and NYT bestselling author N. K. Jemisin. Every great city has a soul. Some are ancient as myths, and others are as new and destructive as children. New York? She's got six. When a young man crosses the bridge into New York City, something changes. He doesn't remember who he is, where he's from, or even his own name. But he can feel the pulse of the city, can see its history, can access its magic. And he's not the only one. All across the boroughs, strange things are happening. Something is threatening to destroy the city and her six newborn avatars unless they can come together and stop it once and for all"
