The Radium Girls by Kate Moore, 479 pages

The Curies' newly discovered element of radium makes gleaming headlines across the nation as the fresh face of beauty and the wonder drug of the medical community. From body lotion to tonic water, the popular new element shines bright in the otherwise dark years of the First World War.
Hundreds of girls paint watch faces amidst the glowing dust of the radium-dial factories. The glittering chemical covers their bodies from head to toe; they light up the night like industrious fireflies. With such a coveted job, these "shining girls" are the luckiest alive-until they begin to fall mysterious ill.
But the factories that once offered golden opportunities are now ignoring all claims of the gruesome side effects and the women's cries of corruption. As the fatal poison of the radium takes hold, the brave shining girls find themselves embroiled in one of the biggest scandals of America's early twentieth century and a groundbreaking battle for workers rights that will echo for centuries to come.
Written with a sparkling voice and breathneck pace, The Radium Girls fully illuminate the inspiring young women exposed to the "wonder" substance of radium and their strength in the face of almost impossible circumstances. Their courage and tenacity led to life-changing regulations, research into nuclear bombings, and ultimately saved hundreds of thousands of lives.
I really enjoyed this book. It was fascinating and kept me engrossed the whole time.
