Lilac Girls is a World War II historical fiction book focusing on Ravensbruck, a women's concentration camp where some prisoners endured cruel experimental surgeries. Chapters alternate between the perspectives of three different women: former actress and wealthy American, Catherine Ferriday, who sends care packages to orphaned children overseas; Kasia, a Polish teenager and Ravensbruck prisoner; and Herta Oberhauser, a German doctor performing experiments in Ravensbruck.
Before reading this book, I hadn't heard of the Ravensbruck Rabbits, but found their story, which is based on real people and real events, so interesting that it prompted me to research further into their lives.
