Galactic North is a collection of eight same-universe Alastair Reynolds stories. More or less this is an adjunct to the Revelation Space universe. Most are pretty interesting, though the typesetting on the Kindle made it preposterously confusing what was going on in Galactic North itself, until I figued out that the headings were just inline in the text. Reynolds admits as much, but without having even read books from the rest of the series, this has a similar feel to the Culture novels. Some neat ideas here, and they’re all quick reads.
