Treaty Planet: Anne McCaffrey and Jody Lynn Nye

Book III of Doona. The huge black spaceship in orbit around Doonarrala is apparently unarmed and poses no immediate threat, but a classified military tape reveals that it bears a striking resemblance to one found derelict and looming over a planet devastated by war. For Todd Reeve, leader of the Human colony on Doonarrala, and for his Hrruban friend Hrriss, the ship represents a chance for both their species to extend the hand of friendship to another. For others, both from Earth and Hrruba, the ship and its inhabitants are a threat of such magnitude they will stop at nothing to to sabotage Todd's efforts at communication.
