Cyborg Liberation - Diaspora Worlds, #7

Ursa boarded the cruiser to join an agricolony on a newly opened plant. She'd had enough heart pounding excitement and danger in ten years in the military. Now she wanted a slow paced, healthy life.  When the cruiser goes off course and arrives at a remote planet with a history of cyborg processing, pregnant ex-soldier Ursa and Zh Cle' math teacher Rhys are thrown together to survive. Cyborg Harvesters search for survivors, so they hide in the wilderness, taking care of young ones who escaped the crash sites.
In all this chaos, Ursa and Rhys acknowledge the passionate attraction between them. Then the Harvesters find them.
