Catalyst: A Rogue One Novel

I really enjoyed this book. It tied in perfectly with the Rogue One movie and did an excellent job of explaining a lot of the back story that makes the movie more complete. The book did a great job demonstrating how the empire took root through the eyes of several characters both within the empire and on the fringes. It also gave Krennic, Galen and Lyra a lot more depth. If you like Star Wars and/or Rogue One, I highly recommend this book.
