Clan and Crown
For the first few years, Rick Galloway and his band of mercenaries were
doing well just to survive. They'd been swept off a hilltop in Africa
by a flying saucer, and deposited on an alien world where the other
inhabitants were human – but from various and unfriendly periods of
history, all collected by flying saucer raids.
Rick has faced facts: This planet is going to be home, permanently. And
to create a society safe for themselves and the families they are
gradually building, they need to do more than just survive. They must
convince the others that a unified, peaceful society is better than a
collection of warring tribes. Force would not be Rick's chosen method
of persuasion – but on a planet where the other dominate culture is one
brought straight from ancient Rome, force may be the only way.
