I love how Becky explores social topics in a sci-fi setting.
Record of a Spaceborn Few describes the lives of humans who now lived for generations as space nomads in a fleet of space ships launched after Earth stopped being liveable.

Topics that are described are:
- what is home? (Everything can be home)
- human culture as seen from an alien species
- Space nomads versus settlers
- the influence of (new) technology on culture
- technology vs. nature

This is the 3rd book from the Wayfarers series, but is the least well written. There are just too many different characters and storylines that it's hard to keep track of them and this slows the book down considerably.
