Excellent scifi. Cibola Burn is the fourth part of The Expanse, and the series just keeps on giving. Every book is exactly what I want to read – difficult situations, new worlds, people who are consistent and neither good nor evil (except for Naomi, of course), but just live their lives. Cibola Burn felt very much like I’d fear the exploration of thousands of suddenly appearing new worlds would go. I think if you think too hard about the technology level displayed in the series, some missing (AI, among other things) tech doesn’t make a whole lot of sense, but I’m willing to forgive this for the vast, technologically and psycologically sound universe.
