The Purge of Tremors by Russell Smith

A young girl and her family escapes the Nazi occupation of Yugoslavia to neighboring Albania. A talented violinist, Dijana is recruited by the exiled Albanian government and the U.S. to use her skills in a dangerous plot to arm and recruit fighters to overthrow the Italian/Nazi occupation. Terrified of the demented Nazi Commandant Rudolph Albrecht sexual advances and the murder of her mother by German soldiers, she uses her beauty and musical skills to seduce Albrecht in a effort to impassion the patriotic fervor of her audiences through her concerts.
