Leviathan Wakes is the first book in the Expanse series by James S. A. Corey (a pen name for for co-writers Ty Franck and Daniel Abraham). If you prefer to watch instead, it is currently being produced as a 10 episode series for the SyFy channel. My husband wanted to read the book before seeing the show so he started in on it. After about a third of the book, he insisted I also had to read it before watching the show. He wasn't too far into the second book when he asked for the third.
In this universe, set a few hundred years in the future, humanity has managed to colonize the solar system but hasn't yet reached the stars. The crew of a small ice hauler responds to a distress signal, and it all goes horribly, horribly wrong from there. Earth groans under the weight of 30 billion hungry mouths and doesn't get along with Mars or Luna. Those three all look down on the 50 to 100 million Belters living on asteroids in the outer solar system. The Belters live a hardscrabble life taxed into poverty by the inner system and resent the folks born into a gravity well. When the ice haulers point the finger at Mars for the death of the ship, they find that things get ugly very, very fast. The more sensible scramble to keep systemwide war from breaking out but the rest just add to the chaos. Remember, you don't need bombs if you can just push a big rock down a gravity well, so the wiser heads are terrified of humanity wiping itself out.
Once I got my turn with book one, I found this to be an action-packed title that alternates between two main characters who feel like believable men. You see a great deal of the life in the "Belt" and it's a rough place. Mistakes very quickly equal dead and the justice is quite frontier in style. Pretty much any consensual vice you can imagine appears to be legal but nobody bats an eye that an engineer that neglected some life support systems fell out of an airlock with some pretty terrible injuries. The science part of the science fiction does have a great deal of "handwavium", but it feels real. The reader is given little details like how many years it took to put a stable spin on a larger asteroid so it would have some gravity for the inhabitants.
I think that the setting and flavor of Leviathan Wakes would appeal to anyone who has the good taste to have loved Firefly. It’s nice to see a new set of “big damn heroes”! I don't know that I hold out the greatest of hopes for the tv. show being as good as the books, but if they stick to the exciting story and interesting characters there's hope! Even the tv show turns out to be awful, the books are well worth reading if you like space-set science fiction at all.
