There's one hugely important scene in this novel which I never saw coming, but loved; Luke having to really question the conduct of the Jedi within the laws of the New Republic. The senate are finally asking the right questions, questions to which Luke cannot give convincing arguments to. It gives a fascinating new perspective to the Jedi, perhaps they aren't so perfect after all?
This kicks off a new quest for the grandmaster, along with his son (with whom he has some brilliant banter along the way, I love their relationship). We also get to visit the home world of Jedi Master Plo Koon (my favourite Jedi), as Luke investigates the reasons for his nephew's downfall in the previous series of novels. Luke becomes a detective, and again it's a really interesting portrayal, and I love the more relaxed approach of the older and wiser Luke, watching and allowing his son to make mistakes so he can teach him important lessons.
I think it's a great kickoff to the latest series of novels in the New Republic Era.
