So, read the novelisation today - truly excellent, Freed's two for two.
The novel takes full advantage of its medium to do what the film cannot, which is put us into the heads of the characters, which in turn casts new light on their outlook and actions. All the characters benefit from this, particularly Krennic, who here is far more his Catalyst self. At the same time Freed heightens both Krennic's ambition and foolishness - he truly thinks he can be the Emperor's second-in-command, in charge of the Death Star, above even Vader! It's entirely believable that Krennic would think this, while to the reader it is laughably impossible.
The break sections with various memos and other info make for a superb set of additions, particularly the one where the addition of the exhaust port is authorised - the language there is very close to actual government style! Equally good is the summary of the setting up of the Rebellion and later, Raddus' belief as to the primary target of the Death Star and he's not wrong.
Absolute excellence, someone get Freed on another SW book quick.
