THE BEST-SELLING RING OF FIRE SERIES CONQUERS THE NEW WORLD
It has taken almost five years for the United States of Europe to stabilize its position in 17th-century Europe. Now it turns its attention to the New World, where the English have ceded their colonial claims to France. There are vast lands and rich resources across the Atlantic for any nations powerful enough to rule and control them--and equal incentive for other nations to block their path.
The time-displaced Americans know about the future path that led to their own United States in North America, in the other universe they came from. But do they want to repeat that history as it was? Yes, they had democracy--but they are helping to create that in Europe. And they have learned the bitter prices paid for chattel slavery and the near-extermination of the native populations.
Knowledge is power. Perhaps a new course can be taken. Accordingly, an expedition is sent to the New World to see just what might be happening there and what might be done. They are armed with their technology, among which are a radio and an airship. More importantly, they are armed with the knowledge of future history and their determination not to repeat the errors of their past.
What could possibly go wrong?
