The Eternal Enemy
by Michael Berlyn
"Unable to comply with an insane spaceship commander's decision to destroy a harmless race of intelligent beings known as habers, xenobiologist Markos flees from his crewmates and dies in a planetside crash—only to reawaken in an alien body for the purpose of teaching the habers the meaning of 'War.' Berlyn uses human and alien viewpoints skillfully to explore the many faces of conflict in this unusual and thoughtful sf adventure." —Library Journal
