This was the perfect balance between lore and pacing! The book gives insight on the flaws of the New Republic and rise of the First Order that wasn't really explained in the movies; while still presenting an interesting narrative with both well known characters and new ones.
I also really appreciate the references to other Gray's works, Lost Stars and Leia: Princess of Alderaan, and nods to comics and other author's details; it makes the universe feel much more real and full of life!
