I just finished the book, and I had mixed feelings.
On the one hand, I liked Mara's journey, and I liked how well Han was written. I really liked the Hand of Judgment, though except for LaRone they all kind of seem the same.

I liked the various manipulations done by both Thrawn and Nuso Esva, but I didn't feel that Esva's motivations were either very well established, or just generic. He hates Thrawn, he wants to conquer, etc. But that doesn't seem to be enough for me. Also, I felt a bit cheesed that Lord Odo was Esva all along and not Thrawn. I mean, Thrawn's full name is Mit'thrawnuruodo (I think I missed an apostrophe in there). Seems like a dead giveaway. I assumed that Odo was Thrawn and Sorro was Car'das, but then it turns out they're on a whole other ship that just happens to be following Chimaera the whole time? I would've preferred that Odo be Thrawn, and Esva simply have agents deep in Chimaera's command structure.
I'll admit, this next comment is based heavily on the fact that I read this sporadically over many weeks, but I just couldn't get into it as much as I wanted to. If I enjoyed it more from the get-go, I'd've been more motivated to keep with it, but nay.
