If you haven't already seen the movie, I'll try not to give anything away. In the first Star Wars canon book/movie in 10 years, we learn that the Rebels now have a new dark sinister government organization to fight against. From the ashes of the Empire, the First Order has arisen. Luke Skywalker is missing, and a very large weapon that makes the Death Star look like a picnic is almost operational. New characters like Rey, Finn, Poe Dameron, Kylo Ren, and BB-8 are introduced, and old favorites like Han Solo, Chewbacca, and Leia are back.
I listened to the audiobook and really enjoyed it. Besides doing a great job with the voices by the narrator, there were background noises and music which gave it a radio drama feel that I appreciated.
