The Best of All Possible Worlds

This book seems like it might be a multiverse story but it mostly isn’t. I’m not sure how it wound up on my radar, but it’s about a few different and distinct types of humans who wind up together on a planet after the destruction of one of the race’s planets. There’s a lot of travel, exploration of other cultures on the planet, a little bit of relationship stuff (there’s a high value placed on marriage and also the destroyed planet’s survivors want to preserve their culture). There’s some good “where did this book come from?” explanation in the afterword. I liked it. It was sort of snoozy and not much happens but the world building and culture building are interesting.
