Kelly's WWII novelization of the story of the Ravensbrück Rabbits, a group of Polish women horribly experimented on during the war was educational if not exactly emotional. Since Caroline and Herta were real individuals, Lilac Girls you don't get the satisfying wrap up you could if the novel was completely fictional. Instead, you just learn another horrible thing that happened during WWII which, while interesting, doesn't captivate the attention since Kelly doesn't play on your emotions.
