I have few to no problems with this book. It was well-written, engaging, and tied in very nicely both with the book that preceded it and the book that followed it.
My qualms are minor. While I agree that people who speak in a certain way frequently use the same mannerisms and sayings over and over, I don’t think it was necessary to rip quotes straight from the films for the characters we encounter in them – Han and Lando don’t need to quote themselves to sound like them. The design of the characters ought to do that for us. Should they speak in the same style, say similar things, etc.? Sure. But I thought I was reading about Han and Lando much more accurately when I imagined them speaking in the voices of Harrison Ford and Billy Dee Williams, respectively, than when I read lines they had in the films.
All-in-all, a worthy addition to the first in the trilogy. Worth a read.
