I just finished reading Nova War by Gary Gibson.
This continues the story of Dakota from Stealing Light. In that book I was pleased at the strong ending, noting that the end of Against Gravity sucked a little. Unfortunately, the end of this book was also very flat, but it is clearly a lead in to the third in the series, which I have high hopes for. When Gibson is writing well, it's really really good, and chunks of this book go there. I get the feeling though that this book and the next should really be just one novel. Sometimes writers get screwed by the publishers like that.
Anyway, there was plenty of big action, but I'm going to hold off on a final decision until I've read Empire of Light.
