The sequel to Beyond the Hallowed Sky, which I read at the start of last year.
It’s an excellent followup, with a very good summary of the previous novel at the start, which is useful. Top quality SF with politics. Scotland, and the Union (the EU++), are expanding into interstellar space, joining the other two power blocs.
Like the last, and perhaps even more so, this ends in a place that is quite satisfying. No cliffhangers, and if there were no more books, it wouldn’t matter.
Though at the same time it’ll be great to see what happens in book 3.
