I just finished reading Leviathan Wakes by James S. A. Corey.
Wow. This was really good. Oh my god. I don't want to give out spoilers, but; Vomit. Zombies. In space.
Also, my favourite quote "Something out there has a comm array that'll put a dot the size of your anus on us from over three AU away".
Much of what I enjoyed through this novel was the plausibility of the tech, the economics and the politics. A very solid picture of how communities work day to day in the mid solar system was detailed over the course of the novel, which as a backdrop to the action and drama made it all the more enjoyable. I notice now it was nominated for a Hugo in 2012, and I can certainly agree with that.
I also enjoyed the main characters, particularly Miller the cop who gets far too attached to the girl he's looking for, even though all he's ever done is look at pictures and read her email. Gritty and flawed, but consistent in his approach and world view, and certainly driven from his experience on the Ceres outpost in the Belt.
Definitely read this one, and there are more to come too.
