The Only Woman in the Room by Marie Benedict

She possessed a stunning beauty. She also possessed a stunning mind. Could the world handle both?
Her beauty almost certainly saved her from the rising Nazi party and led to marriage with an Austrian arms dealer. Underestimated in everything else, she overheard the Third Reich's plans while at her husband's side, understanding more than anyone would guess. She devised a plan to flee in disguise from their castle, and the whirlwind escape landed her in Hollywood. She became Hedy Lamarr, screen star.
But she kept a secret more shocking than her heritage or her marriage: she was a scientist. And she knew a few secrets about the enemy. She had an idea that might help the country fight the Nazis...if anyone would listen to her.
A powerful novel based on the incredible true story of the glamour icon and scientist whose groundbreaking invention revolutionized modern communication, The Only Woman in the Room is a masterpiece.
