I would definitely recommend the fifth science, the various different short stories provide very interesting insights into certain subjects that haven’t really been touched upon in too many science fiction writers because they are either too depressing or too hard to make interesting, but Exurb1a manages to explore these topics and make them extremely enjoyable. Some of the stories are a bit worse than others, but the length of these stories is short enough that it doesn’t feel like a chore to get through them. This book is definitely worth a read.
