Pretty good SF adventure story. Sort of like a western in space. I enjoyed it.
3+ stars, but I cannot quite round it up.

A good synopsis of things we don't know/understand in the world of physics and astrophysics.
Neil deGrasse Tyson is always easy to listen to.

A bit of a different take on TEOTWAWKI. In this case it is due to EMP level radiation from a nearby supernova. It is a pretty good story overall, but I found I really couldn't relate to the characters. YMMV.

Pretty damn good portal story. ‘Nuf said, I reckon.

Re-read after many years. Still good – an SF classic.

Very well written and well researched, this book should be required reading for anyone interested in the end of the Western Roman Empire.
Very good indeed.

The Murderbot is a bit lugubrious, and it doesn't really like people very much. The Murderbot is lonely but doesn't know it. The Murderbot is also is very dangerous, and it has found a mission.

Another good entry in the Murderbot series. Thank you Martha Wells.

Another good book in the Saxon series.

Surreal, and sweet, and sad, and very well written.
4+ stars

Multi-layered and very well written, AMCE is a good science-fiction murder mystery with lots of court intrigue. I will look for more from Arkady Martine.

What a hoot! In Wen Spencer's slightly nutty rural fantasy Dugan meets a talking bear, an angel, and a very nasty dverger. Perhaps he isn't crazy after all.
You can find it in Baen Free Stories 2017.
