Freedom's Ransom - Anne McCaffrey

Freedom's Ransom is the fourth novel in the Freedom series.

The Eosi are defeated. Earth is liberated. Botany is thriving. The problem is all the goods that were looted from Earth are still on the Catteni planet Barevi. They won't part with them without something in return. Zainal, Kris, and the rest of the Botany crew have to find a way to ransom the goods. Challenge accepted. Very highly recommended.
