I enjoyed it and while still far behind Orion's Hounds (it's the one to beat IMHO), I think I enjoyed it more than Sword for sure and Red King as well.
I do like having an exploration book for the first time in a while. I have done the Resistance through Destiny novels pretty much solid for the last 3 months. I have to admit by the time I got through Singular Destiny I was getting depressed with the state of the galaxy. That being said this was a nice book and I actually like how the Ree sub-plot was handled, though I feel that some more follow-up (like the trial) could have helped resolve it.
Overall it was quite decent, so congrats there Christopher!
Now to stalk that new Vanguard novel...
