Historical fiction based on the life of Lyudmila Pavlichenko, a real life Russian sniper credited with over 300 Nazi deaths, who later became a propaganda hero and friend to Eleanor Roosevelt. Quinn digs into the historical record and creates an amazing character out of an amazing real person; her Lyudmila is prickly and impatient, steely and dangerous, full of heart and spirit (and the other characters are amazing too). As usual with Kate Quinn books, both the grit of her heroines and the horrors of war came fully to life; for me the climactic final duel strained belief, but I loved reading it all the same.
