Radium Halos is historical fiction based on the true events of the Radium Dial Painters, a group of female factory workers who, in the early 1920s, contracted radiation poisoning from painting luminous watch dials with radium paint. Our narrator is Helen Waterman, a 65-year-old mental patient who worked at the factory when she was 16. She tells us her story through flashbacks, slowly revealing her past, the loved ones she's lost, and the dangerous secrets she's kept all these years. Includes a Foreword by Leonard Grossman, son of the attorney for the Radium Dial painters.
