I'm a fan of the series, but not a fan fan. That means it has been a while since I've seen the movie. It also means that my memory of it is sketchy. So when I was reading this, I was trying to match it up in my head with the movie, and then things kept getting further apart.
So here's the thing. It is a fun space-opera thing that has some similarities to a famous movie. It can be enjoyed as a stand-alone book. Or at least that was when I started enjoying it, right around the time I saw Han for the first time and just had to accept that some things were different.
It's worth a read.
