For me, this is currently the high-water mark of modern sci-fi. It's often called "Game of Thrones in space" and while the politics of the setting definitely support that, the humor is a cut above the fantasy series. It's almost like a love letter to both earlier hard sci-fi (like the Red Mars books) and the writing of Douglas Adams or Terry Pratchett. It's not a silly book, but it's not afraid to laugh, and it lacks the "Whedonness" of other popular sci-fi. The jokes and quips are fun, in character, absolutely part of the charm, and never distracting.

This is my 3rd time reading it I think, and the plan is to read the whole series at a go. I don't feel like I'm going to get bored with it, this book was better than I remembered.
