Candle of Distant Earth
The gang all make home to their respective homeworlds. However, Walker and George both decide, just as they find our solar system, that they have “grown” and that now they want to travel. Gee, wish they had decided that before they set out with a whole fleet! And the Villinji who kidnapped them and has been chasing them, well, what do you know? He has a sudden change of perspective and sees that maybe other sentients aren’t just “goods” to be sold. How heartwarming .
Foster forced this ending and it didn’t fit with everything that had gone on before. Glad I never bought these.
