Ward's Island in the East River sits just a short distance from Manhattan, Queens, and the Bronx, yet it has been cordoned off from the rest of New York City. For nearly two centuries, it has been treated as a dumping ground for society's most marginalized-the unhoused, recent immigrants, and people diagnosed with mental illnesses. Even today, its two psychiatric hospitals, homeless shelters, and residential substance-use treatment program house more than one thousand people, but these institutions are fenced off from the athletic fields and green space of the adjoining Randall's Island Park.

Exiles in New York City shares untold stories from Ward's Island, offering a new lens on the city's past and present from the perspective of the marginalized. Philip T. Yanos-a clinical psychologist who grew up on Ward's Island-explores the history of the island alongside the history of urban mental health systems in the United States. Drawing on archival documents and interviews with current residents and staff while weaving in recollections of his own childhood, he traces how the island became a place of exile and brings to life the failings of the approach to mental illness that it represents. This incisive and timely book reveals a part of New York City that has long been hidden in plain sight, and it also considers how to transform Ward's Island for a new era.
