In New York Times bestselling author Fiona Davis's latest historical novel, a series of book thefts roils the iconic New York Public Library, leaving two generations of strong-willed women to pick up the pieces.

It's 1913, and on the surface, Laura Lyons couldn't ask for more out of life—her husband is the superintendent of the New York Public Library, allowing their family to live in an apartment within the grand building, and they are blessed with two children. But headstrong, passionate Laura wants more, and when she takes a leap of faith and applies to the Columbia Journalism School, her world is cracked wide open. As her studies take her all over the city, she is drawn to Greenwich Village's new bohemia, where she discovers the Heterodoxy Club—a radical, all-female group in which women are encouraged to loudly share their opinions on suffrage, birth control, and women's rights. Soon, Laura finds herself questioning her traditional role as wife and mother. But when valuable books are stolen back at the library, threatening the home and institution she loves, she's forced to confront her shifting priorities head on . . . and may just lose everything in the process.

Eighty years later, in 1993, Sadie Donovan struggles with the legacy of her grandmother, the famous essayist Laura Lyons, especially after she's wrangled her dream job as a curator at the New York Public Library. But the job quickly becomes a nightmare when rare manuscripts, notes, and books for the exhibit Sadie's running begin disappearing from the library's famous Berg Collection. Determined to save both the exhibit and her career, the typically risk-adverse Sadie teams up with a private security expert to uncover the culprit. However, things unexpectedly become personal when the investigation leads Sadie to some unwelcome truths about her own family heritage—truths that shed new light on the biggest tragedy in the library's history.

In 1933, twenty-two-year-old Marion Crawford accepts the role of a lifetime, tutoring the little Princesses Elizabeth and Margaret Rose.  Her one stipulation to their parents the Duke and Duchess of York is that she bring some doses of normalcy into their sheltered and privileged lives.
 
At Buckingham Palace, Windsor Castle and Balmoral, Marion defies stuffy protocol to take the princesses on tube trains, swimming at public baths, and on joyful Christmas shopping trips at Woolworth’s. From her ringside seat at the heart of the British monarchy she witnesses twentieth-century history’s most seismic events. The trauma of the Abdication, the glamour of the Coronation, the onset of World War II. She steers the little girls through it all, as close as a mother.
 
During Britain’s darkest hour, as Hitler’s planes fly over Windsor, she shelters her charges in the castle dungeons (not far from where the Crown Jewels are hidden in a biscuit tin). Afterwards, she is present when Elizabeth first sets eyes on Philip.
 
But being beloved confidante to the Windsors comes at huge personal cost. Marriage, children, her own views: all are compromised by proximity to royal glory. In this majestic story of love, sacrifice and allegiance, bestselling novelist Holden shines a captivating light into the years before Queen Elizabeth II took the throne.
