I wasn't sure if I would enjoy this book too much (I'm usually not very interested in the Imperial side of things), but was quite pleasantly surprised. It was great to see how the Free Ryloth movement evolved between Clone Wars and Rebels. My favorite part was definitely all of Vader's inner thoughts. Kemp really presents Vader in a fascinating way (I LOVED how he is still tortured by his past, and how we see the inner struggle between good and evil that Luke sees), and I'm actually glad I didn't read Lords of the Sith until after seeing that final sequence in Rogue One - it gave me stronger visuals to accompany his rage in this book. I also especially loved the character of Isval, particularly her side trip down to the Octagon which gave us a much richer understanding of THAT aspect of Twi'lek culture. A solid contribution to the new canon!
