Caliban's War

The second in James S. A. Corey's The Expanse series follows the further adventures of Jim Holden and the crew of the spaceship Rocinante, in the wake of the events of the first novel. Humanity has settled down to a new post-war normal, but further events shake the fragile interplanetary peace.

I'm still not sure about this series. It's pretty good, and there is a nice realistic feel to the frustrations and dangers of living in space and the differences that will naturally emerge as humanity leaves its home planet. But it'd be nice to have some more personality to the main characters (they are very archetypal, and don't have the honest texture of more fully developed characters).
