Cibola Burn

Cibola Burn (2014) is the 4th in the Expanse series by James S. A. Corey (Daniel Abraham and Ty Franck). I'm a big fan of this series and look forward to reading book 5, which is out in hardback now.

from the back of the book:

NPR calls it "the science fictional equivalent of A Song of Ice and Fire". io9 calls it "an outstanding addition to the Expanse universe" and says, "The Expanse is the best space opera series running at full tilt right now, and Cibola Burn continues that streak of excellence."

SFF World says,

What we have here is a novel with some first contact / planet colonization elements, some ancient alien archaeology/ruins, and political thriller elements, among many other things. Howsoever you cut up the pieces of the whole, all of it makes for a damned fine and fun read.
