Power of the Sword - Wilbur Smith

Sasha Courtney was groomed by his French-born mother to take control of the Courtney Mining and Finance Company, whose font of wealth was sown deep beneath African soil. But Sasha's brother, Manfred, had been trained by his renegade father to be a hunter--of lions, and of men.
As the two boys became men, they took on the extraordinary powers of each parent: Sasha, a man in tune with his continent and its people; Manfred who, like his father, was willing to shape his world with a gun. So when the winds of World War II reached Africa, each brother chose a side…
Now, the future of a young nation is being forged amidst a clash of civilizations, ideals, and blood feuds. And as Sasha and Manfred rise to power, a land of beauty and suffering will be remade--for better or for worse--in an image of their own.
