"The colonists of the planet Montana are accustomed to being ignored. Situated in the buffer zone between two rival human empires, their world is a backwater: remote, provincial, independently-minded. Even as a provisional member of the Republic of Aligned Worlds, Montana merits little consideration--until it becomes the flashpoint in an impending interstellar war"--Dust jacket flap.
