I just finished this book. I really enjoyed it. I used to read a lot of the old EU books, and so many of them were from the Rebel perspective that it was kind of refreshing to get a different take on things. It was also interesting seeing some of the inner workings of the Empire between the end of the Clone Wars and the Original Trilogy. I also enjoyed seeing what made Tarkin the person he was. It was a good yarn.
The Carrion Spike was a cool ship, and I'm interested to know more about its fate. I know that it survived in some form, as it has appeared in the Poe Dameron comic series, but it's interesting that it did not go back to Tarkin. I realize that he got a promotion with the Executrix/Death Star, but the ship seemed to be very personal to him and it's odd that he didn't want to keep it. From the novel, you would almost think that it was beyond repair, if not for that fact that it shows up later in the comics.
I've seen where some have mentioned it as another Imperial huge ship, but with it being such a unique, experimental vessel it doesn't make a lot of sense to have it on the table. I prefer ship classes, rather than one-offs.
What are your thoughts on the book?
