Long Walk Home (Hope of Sudan #1)
DiAnn Mills

American doctor Larson Kerr started working with the Sudanese people out of a sense of duty and has grown to love them all, especially Rachel, her young assistant. But despite the years she’s spent caring for them, her life feels unfulfilled. It’s a void that both Paul and Rachel’s older brother, Colonel Ben Alier of the Sudanese People’s Liberation Army, notice.
When Rachel is abducted, Paul, Ben, and Larson agree to set aside their differences to form an unlikely alliance and execute a daring rescue. Their faith and beliefs tested, each must find the strength to walk the path God has laid before them, to find their way home.
