Incubators for preemies at a Coney Island amusement park? Straitjackets for special needs children in schools? Sounds like something out of a horror movie, but it’s a real part of history. Told by debut author Addison Armstrong, The Light of Luna Park is the story of two women who lived decades apart – nurse Althea and teacher Stella – who were fierce, if not always the most ethical, advocates for their charges. To learn the connection between these women is to go on a journey through the first half of the 20th century.
