On Blackwell’s Island, New York, a hospital was built to keep its patients from ever leaving.
 
With her late parents’ fortune under her uncle’s care until her twenty-fifth birthday in the year 1887, Edyth Foster does not feel pressured to marry or to bow to society’s demands. She freely indulges in eccentric hobbies like fencing and riding her velocipede in her cycling costume about the city for all to see. Finding a loophole in the will, though, her uncle whisks Edyth off to the women’s lunatic asylum just weeks before her birthday. And Edyth fears she will never be found.
 
At the asylum she meets another inmate, who upon discovering Edyth’s plight, confesses that she is Nellie Bly, an undercover journalist for The World. Will either woman find a way to leave the terrifying island and reclaim her true self?
