Another great read from author Becky Chambers. She's definitely become one of my favorite voices in contemporary Sci-Fi.
This time focus of the novel is space exploration. There's some very interesting ideas about gene modifications that could allow humans to be better suited to settle alien planets, but they're not the point here.
What's important is the spirit, the ideas, the ethics that move people that dedicate their entire life to space exploration, sacrificing everything else (literally).
And what can I say about the last few pages? Something must have got into my eyes, since they're all watery. Probably a grain of sand. Right.
