Well, there’s a movie out this week. Whether you see it first thing Thursday night or wait for the weekend, know one thing: The Rogue One books are out on Friday. Namely, the novelization by Alexander Freed (eBook only,) the Rogue One Ultimate Visual Guide by Pablo Hidalgo and The Art of Rogue One. I haven’t seen any of them yet, but based on prior experience I say get the Visual Guide first.
For those looking for a different sort of prequel, there’s Poe Dameron #9 on Wednesday.
