In 1904 Margaret Bennet has it all â€" money, position, and an elegant family home in Newport, Rhode Island. But just as she is to enter society, her mother ruins everything, first with public displays, and finally by disappearing. Maggie's confusion and loss are compounded when her father drags her to Yellowstone National Park, where he informs her that they will remain. At first Maggie's only desire is to return to Newport. But the mystical beauty of the Yellowstone landscape, and the presence of young Tom Rowland, a boy unlike the others she has known, conspire to change Maggie from a spoiled girl willing to be constrained by society to a free-thinking and brave young woman living in a romantic landscape at the threshold of a new century.
