May Books 1) Neptune’s Brood, by Charles Stross

The first of this year’s Hugo nominees which I got after nominations had been announced. It’s set in the same universe as Saturn’s Children but that really doesn’t matter, as it’s a very different book – unusually for SF (though much less unusually for Stross) one of the central themes is future economics, specifically the issue of currency and cash flow between worlds which are separated by light years and where information cannot be transferred faster than the speed of light. On top of a decent plot, there is an excellent underwater city, priests, pirates (who may or may not be insurers), and reflections on the complex family dynamics of bespoke clone sisters. I will still rank Ancillary Justice higher, but this gets a good Hugo vote from me.
