Handsome and spirited, he won the heart of a fiery beauty who became his wife, sharing his driving ambition and his daring dreams.

But neither Antoine nor his adoring Medora were prepared for the hostile reception that greeted them. Together, they weathered trials and tribulations that have become turbulent chapters in American history as violently jealous men stopped nothing to destroy their visions of bringing progress and prosperity to a barren land...
