From the New York Times bestselling novelist, a stunning historical novel that follows the story of Mary Anning and Elizabeth Philpot, two extraordinary 19th century fossil hunters who changed the scientific world forever.

On the windswept, fossil-strewn beaches of the English coast, poor and uneducated Mary learns that she has a unique gift: the eye to spot ammonites and other fossils no one else can see. When she uncovers an unusual fossilized skeleton in the cliffs near her home, she sets the religious community on edge, the townspeople to gossip, and the scientific world alight. After enduring bitter cold, thunderstorms, and landslips, her challenges only grow when she falls in love with an impossible man.

Mary soon finds an unlikely champion in prickly Elizabeth, a middle-class spinster who shares her passion for scouring the beaches. Their relationship strikes a delicate balance between fierce loyalty, mutual appreciation, and barely suppressed envy, but ultimately turns out to be their greatest asset.

From the author of At the Edge of the Orchard and Girl With a Pearl Earring comes this incredible story of two remarkable women and their voyage of discovery.
