Prince Renegade: The Prince of Britannia Saga, Book 5 (Unabridged‪)‬

Hazard King finally managed to win peace with the Swarm, and he stabilized the Marxist Federation and helped create a more democratic new government on Lenin.

The Black Dragon virus, though, continues to kill thousands there, and Imperial Scientists have finally admitted that antidotes are beyond their ability. Worse, it is only a matter of time before the virus makes it off planet, an event that is sure to kill billions and bring down the empire.

But there is hope. If they can find the original virus, the creation of a vaccine may be possible. Unfortunately, there's only one source: Earth, the birthplace of humanity. There is a problem, though. Fearing for the safety of their new worlds after the Exodus, early emperors banned all travel there.

When continued attempts by blockade runners to break the quarantine force Hazard's hand, to protect the Empire, he'll have to defy the edict and travel to Earth. To save the Empire, Hazard will need to become… a prince renegade.
