What is the main conflict in When the Lion Feeds by Wilbur Smith?

When the Lion Feeds by Wilbur Smith is a gripping saga beginning with the introduction of twin brothers in Natal in the 1870's. Sean and Garrick Courtney are as close as two brothers can be, and as different at the same time. Bonded from birth, their lives intertwine. Sean is the dominant brother—his father's favorite, and Garrick is mostly content to follow in his shadow. It is this dynamic that orchestrates the hunting accident leaving Garrick without a leg, and Sean responsible.
