I went into this after watching season one of the TV adaptation beforehand and I was not at all disappointed. Seeing the story through Holden and Miller's eyes was a wild ride that never quite seemed to stop. 
 The entire setting is a new, refreshing change (for me, anyway). Humans are in a transition phase, of sorts. We travel in spaceships and live on space stations, but there's an air of precariousness to it all. We're fragile, we're not quite out into the stars yet, not out of the solar system, but we're exploring and dreaming about going farther. Interplanetary travel has been attained, but we're pushing and striving for the interstellar. (view spoiler)[This desire to branch out and explore is a part of what lands the characters in this book in the shits, to be frank. (hide spoiler)] 
 On top of that - there's tension between those who remain on Earth, those who settled on Mars, and those who went even farther to the asteroid belts - the descendants of whom have changed physiologically, a result of living on space stations away from the gravity of Earth. There's a fair degree of racism throughout the story (flung at each division by each division, though some are more openly aggressive than others), some of which is very confronting (view spoiler)[there's a scene where a Martian woman is beaten in the middle of a crowd of Belters by a thug-type character and subsequently has her neck snapped, all because she's wearing the flight suit of a Martian freight line. (hide spoiler)]but it all comes together to paint a very strained picture of the very (quietly, at first) strained relationship between these three factions. (view spoiler)[This strained relationship is preyed upon and used to hide the machinations of those who are really up to no good. (hide spoiler)] Basically: the Belt is tired of being beholden to Earth and Mars, and Earth and Mars seem to be quietly competing with one another. 
 I'm pretty sure it's a spoiler, so (view spoiler)[I NEED TO KNOW MORE ABOUT THE ALIENS WHO SHOT THE PROTOMOLECULE OUT TOWARDS EARTH. They're described as being god-like... two billion years prior to the start of the story, so what are they like now? I NEED TO KNOW. (hide spoiler)] I've got the next book ready, so I'm going to jump into it immediately, but I just need to know. 
 Honestly, if you enjoy scifi, I'd recommend this. It's a somewhat hefty book, at 560+ pages, but there wasn't a moment where I felt truly bored, there was always something happening to keep me interested. And if you do enjoy this: watch the tv show. I'm peeved that they whitewashed Ade, but apart from that and a few minor tidbits, they translated everything across pretty well for the most part. I can't wait for season two.
