Leap of Faith - Danielle Steel

Marie-Ange Hawkins has the kind of childhood that most people dream of. Freedom, love, security in a beautiful old French chateau. But when Marie-Ange is just eleven, a tragic accident marks the end of her idyllic life.
Orphaned and alone, she is sent to America, to live with her great-aunt on a farm in Iowa. Bitterly resented by the old woman, cut off from everything she has known and loved, Marie-Ange is forced to work tirelessly on the farm, dreaming only of the day she can return to her beloved Chateau de Marmouton.
