Ten years have passed on Tines World, where Ravna Bergnsdot and a number of human Children ended up after a disaster that nearly obliterated humankind throughout the galaxy. Ravna and the pack animals for which the planet is named have survived a war, and Ravna has saved more than one hundred Children who were in cold-sleep aboard the vessel that brought them.
While there is peace among the Tines, there are those among them - and among the humans - who seek power...and no matter the cost, these malcontents are determined to overturn the fledgling civilization that has taken root since the humans landed.
