The previous book, Monsoon, ended with the arrival of the brothers Tom and Dorian Courtney at the Cape of Good Hope. Now - though Tom and Dorian are still more than capable of swinging a cutlass or a fist - it's the turn of their sons, Jim and Mansur, to grow up, fall in love and hack their way to happiness through the serried ranks of the Nguni army, a squad of Dutch scoundrels led by the sinister Captain Koots, and the forces of the treacherous Zayn al-Din, usurper of the Elephant Throne of Oman.
