Book excerpt: Fans of Kate Quinn and Kristina McMorris will love this gripping historical novel based on the true story of the woman who used her codebreaking skills to bring down Prohibition gangsters and WWII Nazis, and who ultimately helped found the present-day CIA. Grace Smith has never been one to conform to society’s expectations. She flees small-town Indiana to seek adventure—and finds more than she bargained for when she’s hired by an eccentric millionaire to learn codebreaking. Soon she’s using those skills to help head the government’s fledgling cryptanalysis unit. During Prohibition, Grace takes up the fight against rumrunners—not to mention Al Capone himself. And as the country careens from one Great War to another, it’s Grace who must crack the secrets of foreign governments, catch spies, and derail saboteurs . . . before it’s too late. With wry wit and sheer grit, she forges her own path as a codebreaker, wife, mother. She’s spent a lifetime going up against powerful men and winning. But as war rages and the stakes grow impossibly high, Grace faces a truly impossible choice: her family or her country?

Book excerpt: The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

A YALSA EXCELLENCE IN NONFICTION FINALIST • A KIRKUS BEST BOOK OF THE YEAR Elizebeth Smith Friedman had a rare talent for spotting patterns and solving puzzles. These skills led her to become one of the top cryptanalysts in America during both World War I and World War II.

She went on to play a major role decoding messages during WWI and WWII and also for the Coast Guard's war against smugglers. Elizebeth and her husband, William, became the top code-breaking team in the US, and she did it all at a time when most women weren't welcome in the workforce.

Available in PDF, EPUB and Kindle. Book excerpt: A Best Book of 2021 by Bloomberg BusinessWeek, Time, and The Washington Post The bestselling author of Leonardo da Vinci and Steve Jobs returns with a “compelling” (The Washington Post) account of how Nobel Prize winner Jennifer Doudna and her colleagues launched a revolution that will allow us to cure diseases, fend off viruses, and have healthier babies. When Jennifer Doudna was in sixth grade, she came home one day to find that her dad had left a paperback titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved. When she read it on a rainy Saturday, she discovered she was right, in a way. As she sped through the pages, she became enthralled by the intense drama behind the competition to discover the code of life. Even though her high school counselor told her girls didn’t become scientists, she decided she would. Driven by a passion to understand how nature works and to turn discoveries into inventions, she would help to make what the book’s author, James Watson, told her was the most important biological advance since his codiscovery of the structure of DNA. She and her collaborators turned a curiosity of nature into an invention that will transform the human race: an easy-to-use tool that can edit DNA. Known as CRISPR, it opened a brave new world of medical miracles and moral questions. The development of CRISPR and the race to create vaccines for coronavirus will hasten our transition to the next great innovation revolution. The past half-century has been a digital age, based on the microchip, computer, and internet. Now we are entering a life-science revolution. Children who study digital coding will be joined by those who study genetic code. Should we use our new evolution-hacking powers to make us less susceptible to viruses? What a wonderful boon that would be! And what about preventing depression? Hmmm…Should we allow parents, if they can afford it, to enhance the height or muscles or IQ of their kids? After helping to discover CRISPR, Doudna became a leader in wrestling with these moral issues and, with her collaborator Emmanuelle Charpentier, won the Nobel Prize in 2020. Her story is an “enthralling detective story” (Oprah Daily) that involves the most profound wonders of nature, from the origins of life to the future of our species.

Available in PDF, EPUB and Kindle. Book excerpt: “What would it be like to keep a secret for fifty years? Never telling your parents, your children, or even your husband?” Codebreaker Girls: A Secret Life at Bletchley Park tells the true story of Daisy Lawrence. Following extensive research, the author uses snippets of information, unpublished photographs and her own recollections to describe scenes from her mother’s poor, but happy, upbringing in London, and the disruptions caused by the outbreak of the Second World War to a young woman in the prime of her life. The author asks why, and how, Daisy was chosen to work at the Government war station, as well as the clandestine operation she experienced with others, deep in the British countryside, during a time when the effects of the war were felt by everyone. In addition, the author examines her mother’s personal emotions and relationships as she searches for her young fiancée, who was missing in action overseas. The three years at Bletchley Park were Daisy’s university, but having closed the door in 1945 on her hidden role of national importance — dealing with Germany, Italy and Japan — this significant period in her life was camouflaged for decades in the filing cabinet of her mind. Now her story comes alive with descriptions, original letters, documents, newspaper cuttings and unique photographs, together with a rare and powerful account of what happened to her after the war. “Here’s a beauty of a history of some of the codebreaking girls who helped save us during the second world war. This one’s about Daisy Lawrence’s extraordinary life as a poor girl brought up in London and then chosen for top secret work at Bletchley Park. Reads like fiction.” —Books Monthly

Available in PDF, EPUB and Kindle. Book excerpt: National Bestseller NPR Best Book of the Year “Not all superheroes wear capes, and Elizebeth Smith Friedman should be the subject of a future Wonder Woman movie.” —The New York Times Joining the ranks of Hidden Figures and In the Garden of Beasts, the incredible true story of the greatest codebreaking duo that ever lived, an American woman and her husband who invented the modern science of cryptology together and used it to confront the evils of their time, solving puzzles that unmasked Nazi spies and helped win World War II. In 1916, at the height of World War I, brilliant Shakespeare expert Elizebeth Smith went to work for an eccentric tycoon on his estate outside Chicago. The tycoon had close ties to the U.S. government, and he soon asked Elizebeth to apply her language skills to an exciting new venture: code-breaking. There she met the man who would become her husband, groundbreaking cryptologist William Friedman. Though she and Friedman are in many ways the "Adam and Eve" of the NSA, Elizebeth’s story, incredibly, has never been told. In The Woman Who Smashed Codes, Jason Fagone chronicles the life of this extraordinary woman, who played an integral role in our nation’s history for forty years. After World War I, Smith used her talents to catch gangsters and smugglers during Prohibition, then accepted a covert mission to discover and expose Nazi spy rings that were spreading like wildfire across South America, advancing ever closer to the United States. As World War II raged, Elizebeth fought a highly classified battle of wits against Hitler’s Reich, cracking multiple versions of the Enigma machine used by German spies. Meanwhile, inside an Army vault in Washington, William worked furiously to break Purple, the Japanese version of Enigma—and eventually succeeded, at a terrible cost to his personal life. Fagone unveils America’s code-breaking history through the prism of Smith’s life, bringing into focus the unforgettable events and colorful personalities that would help shape modern intelligence. Blending the lively pace and compelling detail that are the hallmarks of Erik Larson’s bestsellers with the atmosphere and intensity of The Imitation Game, The Woman Who Smashed Codes is page-turning popular history at its finest.

Available in PDF, EPUB and Kindle. Book excerpt: 'Lively...in giving us the daily details of their lives in the women's own voices Dunlop does them and us a fine service' New Statesman 'Dunlop is engaging in her personal approach. Her obvious feminine empathy with the venerable ladies she spoke to gives her book an immediacy and intimacy.' Daily Mail 'An in-depth picture of life in Britain's wartime intelligence centre...The result is fascinating, and is made all the more touching by the developing friendships between Dunlop and her interviewees.' Financial Times The Bletchley Girls weaves together the lives of fifteen women who were all selected to work in Britain's most secret organisation - Bletchley Park. It is their story, told in their voices; Tessa met and talked to 15 veterans, often visiting them several times. Firm friendships were made as their epic journey unfolded on paper. The scale of female involvement in Britain during the Second World War wasn't matched in any other country. From 8 million working women just over 7000 were hand-picked to work at Bletchley Park and its outstations. There had always been girls at the Park but soon they outnumbered the men three to one. A refugee from Belgium, a Scottish debutante, a Jewish 14-year-old, and a factory worker from Northamptonshire - the Bletchley Girls confound stereotypes. But they all have one common bond, the war and their highly confidential part in it. In the middle of the night, hunched over meaningless pieces of paper, tending mind-blowing machines, sitting listening for hours on end, theirs was invariably confusing, monotonous and meticulous work, about which they could not breathe a word. By meeting and talking to these fascinating female secret-keepers who are still alive today, Tessa Dunlop captures their extraordinary journeys into an adult world of war, secrecy, love and loss. Through the voices of the women themselves, this is a portrait of life at Bletchley Park beyond the celebrated code-breakers, it's the story of the girls behind Britain's ability to consistently out-smart the enemy, and an insight into the women they have become.

As the threat to her fellow codebreaker girls grows ever stronger, Rosie realises her country needs her more than ever. Can she save the day without losing her heart? A heartwarming, funny and utterly charming World War II saga, perfect for fans of Kate Hewitt, Jenny Holmes and Annie Murray.

Book excerpt: “The reigning queen of historical fiction” -- Fiona Davis, New York Times bestselling author of The Lions of Fifth Avenue The New York Times and USA Today bestselling author of The Huntress and The Alice Network returns with another heart-stopping World War II story of three female code breakers at Bletchley Park and the spy they must root out after the war is over. 1940. As England prepares to fight the Nazis, three very different women answer the call to mysterious country estate Bletchley Park, where the best minds in Britain train to break German military codes. Vivacious debutante Osla is the girl who has everything—beauty, wealth, and the dashing Prince Philip of Greece sending her roses—but she burns to prove herself as more than a society girl, and puts her fluent German to use as a translator of decoded enemy secrets. Imperious self-made Mab, product of east-end London poverty, works the legendary codebreaking machines as she conceals old wounds and looks for a socially advantageous husband. Both Osla and Mab are quick to see the potential in local village spinster Beth, whose shyness conceals a brilliant facility with puzzles, and soon Beth spreads her wings as one of the Park’s few female cryptanalysts. But war, loss, and the impossible pressure of secrecy will tear the three apart. 1947. As the royal wedding of Princess Elizabeth and Prince Philip whips post-war Britain into a fever, three friends-turned-enemies are reunited by a mysterious encrypted letter--the key to which lies buried in the long-ago betrayal that destroyed their friendship and left one of them confined to an asylum. A mysterious traitor has emerged from the shadows of their Bletchley Park past, and now Osla, Mab, and Beth must resurrect their old alliance and crack one last code together. But each petal they remove from the rose code brings danger--and their true enemy--closer...

Book excerpt: Protesters called it an act of war when the U.S. Coast Guard sank a Canadian-flagged vessel in the Gulf of Mexico in 1929. It took a cool-headed codebreaker solving a "trunk-full" of smugglers' encrypted messages to get Uncle Sam out of the mess: Elizebeth Smith Friedman's groundbreaking work helped prove the boat was owned by American gangsters. This book traces the career of a legendary U.S. law enforcement agent, from her work for the Allies during World War I through Prohibition, when she faced danger from mobsters while testifying in high profile trials. Friedman founded the cryptanalysis unit that provided evidence against American rum runners and Chinese drug smugglers. During World War II, her decryptions brought a Japanese spy to justice and her Coast Guard unit solved the Enigma ciphers of German spies. Friedman's "all source intelligence" model is still used by law enforcement and counterterrorism agencies against 21st century threats.

But as nurse Arabelle Denler watches the so-dubbed "Black Heart" every day, she sees something far different: a hurting man desperate for mercy. And when their paths twist together and he declares himself her new protector, she realizes she has her own role to play in his healing. Phillip Camden would have preferred to die that day with his squadron rather than be recruited to the Admiralty's codebreaking division. The threats he receives daily are no great surprise and, in his opinion, well deserved. What comes as a shock is the reborn desire to truly live that Arabelle inspires in him. But when an old acquaintance shows up and seems set on using him in a plot that has the codebreakers of Room 40 in a frenzy, new affections are put to the test.

Book excerpt: Based on the true story behind a landmark U.S. Supreme Court Decision, K.D. Alden's debut is a rich and moving story of one woman's courage and determination to get her child back when all odds are stacked against her. Virginia, 1927: All Ruth Ann Riley wants is a chance to have a family. But because she was poor and unwed when she became pregnant, she was sent to an institution and her child was given to another woman. Ruth Ann can't stand the thought of never seeing little Annabel's face again, never snuggling up to her warmth or watching her blue eyes crinkle with laughter. And now they want to take away her right to have any other babies? She is not going to let that happen. All the rich and fancy folks may call her feebleminded, but Ruth Ann is smarter than any of them have bargained for. Because no matter how high the odds are stacked against her, she is going to overcome the scandals in her past and get her child back. She just never expects her battle will go to the U.S. Supreme Court, or that she'd find unexpected friendships . . . and even the possibility of love along the way.

Available in PDF, EPUB and Kindle. Book excerpt: In 1942, with a black-market chicken tucked under his arm by his mother, Leo Marks left his father's famous bookshop, 84 Charing Cross Road, and went off to fight the war. He was twenty-two. Soon recognized as a cryptographer of genius, he became head of communications at the Special Operations Executive (SOE), where he revolutionized the codemaking techniques of the Allies and trained some of the most famous agents dropped into occupied Europe. As a top codemaker, Marks had a unique perspective on one of the most fascinating and, until now, little-known aspects of the Second World War. This stunning memoir, often funny, always gripping and acutely sensitive to the human cost of each operation, provides a unique inside picture of the extraordinary SOE organization at work and reveals for the first time many unknown truths about the conduct of the war. SOE was created in July 1940 with a mandate from Winston Churchill to "set Europe ablaze." Its main function was to infiltrate agents into enemy-occupied territory to perform acts of sabotage and form secret armies in preparation for D-Day. Marks's ingenious codemaking innovation was to devise and implement a system of random numeric codes printed on silk. Camouflaged as handkerchiefs, underwear, or coat linings, these codes could be destroyed message by message, and therefore could not possibly be remembered by the agents, even under torture. Between Silk and Cyanide chronicles Marks's obsessive quest to improve the security of agents' codes and how this crusade led to his involvement in some of the war's most dramatic and secret operations. Among the astonishing revelations is his account of the code war between SOE and the Germans in Holland. He also reveals for the first time how SOE fooled the Germans into thinking that a secret army was operating in the Fatherland itself, and how and why he broke the code that General de Gaulle insisted be available only to the Free French. By the end of this incredible tale, truly one of the last great World War II memoirs, it is clear why General Eisenhower credited the SOE, particularly its communications department, with shortening the war by three months. From the difficulties of safeguarding the messages that led to the destruction of the atomic weapons plant at Rjukan in Norway to the surveillance of Hitler's long-range missile base at Peenemünde to the true extent of Nazi infiltration of Allied agents, Between Silk and Cyanide sheds light on one of the least-known but most dramatic aspects of the war. Writing with the narrative flair and vivid characterization of his famous screenplays, Marks gives free rein to his keen sense of the absurd and wry wit without ever losing touch with the very human side of the story. His close relationship with "the White Rabbit" and Violette Szabo -- two of the greatest British agents of the war -- and his accounts of the many others he dealt with result in a thrilling and poignant memoir that celebrates individual courage and endeavor, without losing sight of the human cost and horror of war.
