Book excerpt: Severus follows the amazing true story of a rebellious boy who grew up in an African province and became the first Black Caesar of the Roman Empire, the head of a dynasty that would lead Rome through bloody civil wars and rapidly changing times. As a young man, Severus hates the Romans and conspires to humiliate them. What begins as a childish prank unfurls into a bloodbath that sends Severus careering into his future. Through a tragic love affair, dangerously close battles and threats both internal and external, Severus accrues power -- and enemies -- in his unlikely rise to become the most powerful man in the ancient world.
