I'm not quite as gushing as the praise that has been heaped on this book. It is very pleasant to read, but it is, for me, somewhat forgettable. It is to be praised for its brevity, many authors would have felt compelled to make this longer, but it doesn't need to be.

There is no plot as such, it's mostly the thoughts of the astronauts co-mingled with the orbits of the ISS around earth.

I wouldn't heartily recommend this as a must read, but at the same time I wouldn't caution someone not to bother, if it appeals to you, then it's probably worth it for you.
