What Happens to a Ship Once it Reaches Its Destination?

The third book in Becky Chambers' Wayfarer series, Record of a Spaceborn Few, is slower and more philosophical than the first two in the series; the Exodans left earth, traversed the galaxy, encountered various alien races, and were admitted into the GC (Galactic Commons) and while most humans have colonized planets and assimilated into the galactic community as best they can (despite the rank smell that humans emit) there are still folks living on the generational ships that sheltered the earthlings on their long voyage-- they maintain the ships as a tribute to the journey but sometimes life seems futile to these people, as they when live onboard something that has already fulfilled its purpose-- this is a slice of life type of sci-fi novel that covers a number of characters in various circumstances aboard an Exodan ship-- it's smart and well-written but not as funny as the first two in the series.
