I always enjoy reading these epic Wilbur Smith novels of Africa. There is great culture and history, and while not great literature, the good guys are always really good, and the bad guys are always really bad. You know exactly what you are getting in one of these stories. This particular story finishes a prequel trilogy that tells the origin story of the Courtney family from the Age of Sail.
A common criticism is Smith's treatment of women and that is absolutely fair. On the one hand, the female characters are always strong and insert themselves into important decisions in the story, but on the other hand, they always end up fully accepting their roles as the domestic rulers. Also, every good woman has a huge sexual appetite in Smith's stories - clearly these books are written with a heavy masculine point of view.
For me, these are the historical fiction version of James Bond movies - just have to let go and enjoy.
