When the Nazis attack the Soviet Union, Nina Markova risks everything to join the legendary Night Witches, an all-female night bomber regiment. When she is stranded behind enemy lines, Nina becomes the prey of a lethal Nazi murderess known as the Huntress. Transformed by the horrors he witnessed, British war correspondent Ian Graham has become a Nazi hunter. Yet one target eludes him: a vicious predator known as the Huntress. To find her, the fierce, disciplined investigator joins forces with the only witness to escape the Huntress alive: the brazen, cocksure Nina. But a shared secret could derail their mission unless Ian and Nina force themselves to confront it.
