"The Rose Code" takes readers back to the heart of World War II with a riveting tale of espionage, sacrifice, and the power of friendship. At Bletchley Park, Osla, Mab, and Beth come together, united by their exceptional abilities to break Nazi codes. Osla, a glamorous debutante, yearns to be more than just a pretty face and uses her German skills to make a difference. Mab, molded by the hardships of East-End London, diligently manipulates the Park's famed machinery. Beth, a shy local, emerges as a talented cryptanalyst, outshining her modest origins. Amidst the war's chaos, the women forge a bond that promises to last a lifetime. But when hostilities cease, a mysterious letter bearing an encrypted secret threatens to shatter everything. Tensions rise as the royal wedding of Princess Elizabeth and Prince Philip looms and the former friends must now confront their shared past—and a devious traitor—before it's too late.
