warlock - Wilbur Smith

In the wake of a sixty-year war over the reign of the kingdoms of Egypt, two young pharaohs have risen to claim power, but only one can succeed, deciding the fate of his empire forever...
The mission of Prince Nefer, rightful heir to the throne, is to rebuild a magnificent kingdom in the stark and tumbled ruins of the embattled city of Gallala. The desire of Lord Naja is to destroy his rival and rule the land with unholy supremacy. But Nefer has on his side the warlock Taita, a matchless ally and legendary priest of notorious powers...
To see their dream come true, Nefer and Taita must stay one step ahead of the depraved assassin, survive the tortuous shadow of her ever-pursuing armies, and outwit the shocking betrayals of is own flesh and blood. As Nefer's courage increases, and as Taita's magic grows more beguiling, so grows stronger the power of their tireless enemies
