One of the best space operas I've ever read! Great purchase, will be buying the rest of the series. Why was this so good? 
 1. Awesome characters. I've been watching the TV series based on this world, so I was already familiar with the major players. However, certain things that didn't seem to make sense on the show were made clear, ex., Miller's obsession with finding Julie Mao struck me as creepy on the screen, but here, Miller was an amazing psychological portrait and was my favorite character overall. Also, TV Amis strikes me as a psychopath. He's much more likeable in the book. 
 2. Space-opera set in the Solar System. Sometimes the learning curve on a SF or Fantasy title can be pretty steep, especially when you need to learn the lay of the land. The Expanse books are set in our Solar System though, so all the places are familiar to anyone with a grade school science education. 
 3. Some very good holy sh!t moments. There's a good mix of scary stuff and battle scenes to keep you on the edge of your seat. 
 4. Insightful moments as well. Meaning of life stuff is presented but not overly preachy. The politics and human-nature aspects of the story are believable. 
 5. The Mormons are the first to build a ship to get to the stars. Not NASA. Not the UN. The Mormons. Ha! That's just original. 
 The patrons of my library are going to start hearing a lot about this one. Highly recommended!!!
