Roberta Kagan Book order

Austria 1929 When three little girls-Anna, Bernie, and Elica-make a pact to be blood sisters for life, they believe nothing can come between them. Anna is from an affluent Jewish family, while Bernie and Elica are from poor Austrian families who barely make ends meet. As they get older, their social differences become all too real. With infectious Jew-hate-laden rhetoric from Nazi Germany spreading into Austria, it is only a matter of time before their bond of friendship gets severely tested. How strong is a bond sealed in blood?

As the Nazi shadow of death falls across Europe, one man's wickedness looms out of the darkness. 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. Mengele's Apprentice is the second book in Roberta Kagan's heartwrenching Historical WWII series-The Auschwitz Twins.
