The Long Way to a Small Angry Planet by Becky Chambers is a weird book where practically nothing happens, then you can't stop thinking about it. It has very strong character work.

The sequel, A Close and Common Orbit has a more plot based structure, which is why I like it better, but still has really great character work. The series is called Wayfarers, there are two more.

She also has an unconnected book called To Be Taught, If Fortunate, about space exploration.

I don't think anyone assembles better titles. These are fairly short and don't focus on violence.
