In 1959, Barbara Toy set out to drive from Libya to Ethiopia. Alone, she crossed the Sahara Desert and the equatorial forests of the Congo before ascending the highlands of Haile Selassie's empire. Her Ethiopian travels took her from modern Addis Ababa to the ancient ruins of Aksum, through bandit-ridden countryside to the summit of Mount Wehni - where male heirs to the emperor were traditionally imprisoned for life - on a quest to explore the legend of the Queen of Sheba. Full of good humour and grit, 'In Search of Sheba' chronicles a remarkable feat of endurance and adventure.
