Frozen landscapes, hidden truths... In a world of isolation and deception, fossils reveal untold stories. In the second adventure of the Fossil Woman series, Henrietta Ballantine has her future all figured out. With her Ph.D. in hand, she's ready to embark on explorations and digs alongside her new husband, geologist Frank Bailey. However, she quickly discovers that marriage comes with unexpected compromises. When Frank's company sends him to the remote town of Mammoth, North Dakota, Henrietta's carefully constructed future begins to shatter.

Struggling to find employment in the male-dominated science field of the 1960s and feeling increasingly isolated in their snow-shrouded bungalow, Henrietta grapples with her new reality. Amidst internal struggle about starting a family, her one solace comes from a growing friendship with an enigmatic local Native American woman.

As winter's chill sets in and Henrietta's frustration peaks, a chance encounter reopens the doors to paleontology, propelling Henrietta to a dinosaur dig in the badlands. But all is not what it seems on the dig and suspicion looms as she's shut out by her male colleagues. With unwavering resolve, Henrietta conducts her own research in this barren and sacred land. As a sinister plot emerges, Henrietta must use her wits and determination to uncover unsettling truths buried within the Hell Creek formation. Fossil Thief is a tale of resilience, unearthing the strength to overcome adversity, and the power of unexpected allies in the most trying times.
