The Goddess of Warsaw by Lisa Barr

Los Angeles, 2005. Sienna Hayes, Hollywood’s latest It Girl, has ambitions to work behind the camera. When she meets Lena Browning, the enormously mysterious and famous Golden Age movie star, Sienna sees her big break. She wants to direct a picture about Lena’s life—but the legendary actor’s murky past turns out to be even darker than Sienna dreamed. Before she was a Living Legend, Lena Browning was Bina Blonski, a Polish Jew whose life and family were destroyed by the Nazis.
Warsaw, 1943. A member of the city’s Jewish elite, Bina Blonski and her husband, Jakub, are imprisoned in the ghastly, cramped ghetto along with the rest of Warsaw’s surviving Jews. Determined to fight back against the brutal Nazis, the beautiful, blonde Aryan-looking Bina becomes a spy, gaining information and stealing weapons outside the ghetto to protect her fellow Jews. But her dangerous circumstances grow complicated when she falls in love with Aleksander, an ally in resistance—and Jakub’s brother. While Lena accomplishes amazing feats of bravery, she sacrifices much in the process.
Over a decade after escaping the horrors of the ghetto, Bina, now known as Lena, rises to fame in Hollywood. Yet she cannot help but be reminded of her old life and hungers for revenge against the Nazis who escaped justice after the war. Her power and fame as a movie star offer Lena the chance to right the past’s wrongs . . . and perhaps even find the happy ending she never had.

A gripping page-turner of one of history’s most heroic uprisings and an actress whose personal war never ends, The Goddess Of Warsaw is filled with secrets, lies, twists and turns, and a burning pursuit of justice no matter the cost.
