**Reread update 5/17/17** 
 One big thing that stands out to me going back to this after reading all the available books in the series is that my complaint about distinct bad guys not getting introduced until very late in the stories was addressed. From this point on we almost always have a face of the threat through most of the action, and that's an improvement that made a great series even better. 
 I also wanted to check this out again after seeing the second season of the TV series. The show has gotten so good that I'm now visualizing all the characters as the actors who play them while reading. There's also an interesting dynamic in that that the two-headed writer who makes up the James SA Corey name also works on the show, and since they have the advantage of knowing what's going to happen for the next several books it's able to shade in lot of character nuance and motivations that were just a little thin and simplistic in the early going. 
 So now I'm counting the days until the new book publishes and the next season premieres. 
 (Original review.) 
 Essentially this is a mix of Game of Thrones and Firefly without all the rape and child burning and people talking like they're in a western movie. 
 Humanity has expanded throughout our solar system, colonizing Mars and various moons and asteroids. Since people are always gonna be people, and will therefore suck, political tensions are high between Earth, Mars, and the Belters, and the events of the first book in the series have the threat of war seeming higher than ever. And just like in Westeros everyone is so consumed with their petty scheming and power plays that they're ignoring the much larger threat that is growing under their noses. So it falls to a crew of misfits running their own ship for profit to step in when the shit hits the air recyclers. 
 This on-going space opera has sucked me in to its world...er... solar system completely with its spaceships, action, politics, and weird sci-fi elements mixed with just enough humor and emotional weight to give it some heft beyond its pew!-pew! appeal. The characters are well drawn even if they aren't particularly deep, and their motivations are plainly spelled out in their dialogue. So this is all text, no subtext, but it is entertaining. I particularly liked the new character of Chrisjen Avasarala, a grandmother and UN official from Earth whose little old lady appearance is subverted by her foul mouth and political cunning. 
 However, the series so far has suffered a bit from not giving us any perspective from the vast conspiracy that is causing so much of the trouble. Granted, some of this has been played as a mystery to solve, but for two books now we've gotten no sense of who the bad guys are or what they're planning other than what's been figured out by the heroes. Both books have finally revealed a kind of mid-level mastermind character near the end, and in both cases these have been full on mustache twirling villains so the threat they pose seems kind of vague and cartoonish. 
 Still, this one ends on a helluva twist that has me itching to roll right into the next one, and I couldn't turn the pages fast enough when I was in the midst of this. I'll be happily returning to the Expanse series as soon as possible. 
 Plus, this trailer for the show coming to SyFy based on the series has got me even more excited.
