In 1917, the Radium Luminous Materials Corporation willingly employed young women, paid far better than most businesses, and had many enticing perks—including the glow. But the women would soon suffer horrific pain and grotesquely shattered bones and teeth, and the company, it would be discovered, had known better. This timely work of nonfiction celebrates the strength of a group of women whose determination to fight improved both labor laws and scientific knowledge of radium poisoning.
