Query: A good pre Humanx commonwealth story

This book explors the relationship between humans and thranx in Fosters humanx universe. Glimpse at the events and pressures which started(or should I way jumpstarted) the amalgemation of Humans and thranx into a single multi-star system civilization after their first contact(shown in 'Nor crystal tears'). The charecters are not heroic types and you get a good sense of their frustration and desperation.
