Invisible Sun is not perfect, but it's perfect for me.

The Empire Games trilogy comes to a very satisfying conclusion in this doorstopper of a sci-fi thriller, as multiple plots on multiple timelines collide in a Last Plan Standing kind of situation. The paranoid police state of divergent USA and the fledgling democracy of the NAC have set their schemes in motion and Invisible Sun is all about resolution and payoff. It's competence porn with an incredibly high level of detail, but I cared about the characters and I cared about the big picture and as a result the incredibly tense story worked like gangbusters.

Some will object to the infodumps (I don't), and there is a spattering of editorial carelessness, but this may still be my favourite Charles Stross book of all time.
