Aaaaah!! This was so good. Most good, even. I think I actually liked this more than the first one?

At first I was sad that the previous crew wouldn't be appearing again, but then I ended up loving these characters a lot more. A Closed and Common Orbit tells two stories 20 years apart that eventually meet, and they were both amazing.

I admit that I was more invested in Jane's story and sometimes when we switched to Sidra I was eager to get back to Jane, but Sidra's story was still good.

I especially love that we have two significant AI characters in this book, and they both interact with humans, and it's clear that they're capable of feeling and having relationships with people - BUT these are not romantic relationships like they often are in AI books. Sidra and Owl both form family relationships with humans (and other species) and it's beautiful.

Also, genderfluid alien side character.
