So I got the book at launch and blasted through it in 12 parsecs.. ha ha I mean 2 days..
It was good! It is "expanded" like The Last Jedi novelization, so it adds in some more background details and "what the character is thinking" since you can't do that easily in a movie.
Biggest parts were.. (spoilers ahead)
What happened before the movie starts, the deal that 'went bad' and some more establishing info on what Corellia is like.
It went into what happened to Qi'ra between getting left on Corellia and showing up again. What the Crimson Dawn did to her to whip her into shape.
More background on the SJW droid.. wasn't really all bad, and you get a little bit more character out of it.
Han Solo at the Imperial Academy and what he did to get busted down to infantry.
At the end there is a prologue segment.. where Enfys Nest is taking the coaxium.. turns out she's handing it over to one Saw Gerrera.. and while they're taking, a young Jyn Erso comes down the ramp and talks for a moment with Enfys Nest. It's a very small segment, but it was cool, considering the tie to Rogue One and Rebels.
Lots of other small things that just flesh out the basic idea a little more.. but I enjoyed it!
