Fleeing the Solar System after an attack by North America, the three Home habitats now have to seek their own fortunes. Heather, Sovereign of Central on the Moon, saved them but now has to make certain the USNA can never threaten them again. What was a tentative research partnership with the Red Tree Clan of Derfhome becomes a full alliance of equals. Lee finds she has to grasp authority and act for the Red Tree Mothers and herself to repossess the planet Providence she and Gordon discovered. The Claims Commission on Earth has collapsed without the leadership of North America. Explorers like her are cut off from their payments and the colonists on Providence are left in the lurch too. To do that she needs these powerful new allies.
