This little book pretty much blew me away, with its poetic and beautifully-written ruminations on life, space, and the Earth, featuring six astronauts/cosmonauts on the space station. There were many sections that changed or expanded my perspective on things. It definitely called to mind the Pale Blue Dot. It's not flawless - for example, there were a few times when it felt perhaps a bit too sentimental, and I'm not sure why it referred to "mankind" rather than "humankind" through most of the novel (also, an early description of the Japanese astronaut as being "not-quite definable" veered a little too close to the "inscrutable" trope, I thought). Overall, though, it was extremely well done.
