Mengele, the Angel of Death.

When the Aizenberg family winds up in the dreaded Warsaw ghetto, they must share an apartment with a secular Jewish family. This living arrangement will test young Shoshana Aizenberg as adulthood creeps ever closer.

Meanwhile, fast-rising doctor Ernst saves a man's life on the Russian front. This good deed earns him the coveted role of Dr. Mengele's apprentice at Auschwitz. An opportunity beyond his wildest dreams and the stuff of his nightmares.

Gisele's beauty shines in a life fraught with hardship. She hopes to find her father, but first, she must navigate a Paris crawling with invading Nazis.
