As a standalone sequel, A Closed and Common Orbit did well to outline the setting. I think new readers would be able to understand things just fine. At the same time, it further expanded the world building for those who’ve read The Long Way to a Small, Angry Planet. The characters remained central to the plot of A Closed and Common Orbit as well, thereby justifying the slow pacing.
THE LONG WAY TO A SMALL, ANGRY PLANET by Becky Chambers
My problem with space operas is that usually not much happens besides the characters floating through space. On that front, I felt The Long Way to a Small, Angry Planet fit squarely fit that trope. Conflicts outside of the spaceship didn’t arise as often nor as intensely as I had liked, even with their unpredictable mission and the threat of war looming. The reason I enjoyed this book anyway were the characters. They were absolutely wonderful!
