Wow that took me a whole chunk of time to get through but it was worth it in the end!
I could only manage to read a few pages at a time as I struggled to get my head around the science aspects of the story.
I loved the aspects of connection and relationships. Building communication with Rocky etc.

I was quite sure why he didn’t head back to earth in the end because that was the plan and I don’t think that was ever explained but I think the ending was lovely.
