The Rose Code (Kod Rozy)

The new novel from the 'queen of historical fiction,' Kate Quinn, is a World War II-era story about three codebreakers and the spy they must uncover. In 1940, with England already at war with the Nazis, three very different women meet at Bletchley Park, where Britain's finest minds work in secrecy to decipher German radio messages.
Ozla is a frivolous high society debutante having an affair with Philip, Prince of Greece, who will, a few years later, marry the future Queen Elizabeth. Mab is a stately beauty with a difficult life from a working-class area of ​​London. And Bette is a quiet, mousy woman from a provincial town, living under the tyrannical thumb of her prude mother. They are united by war, unexpected abilities they never knew they had, and work that is strange, interesting, and very important.
'The Rose Code' is a complex interweaving of military history, love stories, spy passions, but above all, a stunningly written story of female friendship during the war years.
