The book started a little slow for me, but then I wasn't used to hard science fiction, but once I got used to all the detail, I began to enjoy it. The research was spectacular, and I feel like I know what it's really like to be an astronaut or to be in mission control (this part really made me think of Apollo 13 and Hidden Figures).
I wanted to be an astronaut when I was a kid, and have always been a science nerd, so I enjoyed the realism and science of it. I also like the diverse array of characters, the clever solutions, the awe of being in space. There was tension with the troubles they found themselves in, a realistic amount of interpersonal getting-on-one-another's-nerves (which we can all relate to, especially during quarantine) but nothing overly dramatic, and some exciting danger. I don't want to say too much so I don't spoil anything, but I've very much looking forward to the next book.
If you like hard science fiction or want to branch out and read something different, check out Random Walk (Fractured Galaxy Book 1) by Rachel Lulich.
