Ultimate Star Wars is one big book! It encompasses the entire Star Wars film saga, The Clone Wars, and Star Wars Rebels all in one volume. It was a daunting task indeed to tackle such an all-encompassing Star Wars encyclopedia.

Writing so much material on a tight schedule — no matter what the subject matter — all comes down to pacing and perseverance. It means diving in to the book each morning, even when you have the flu or feel more than a little sleepy. You get your words down first — inspiration comes along the journey.

The majority of my time was actually spent in research. This means weeks of weeding through piles of books, comics, maps, and diagrams, endless Internet searches, jumping through scenes on DVDs and Blu-rays, recalling gems from podcasts and cast and crew interviews, and keeping John Williams on at all other times for some extra motivation.

My contributions to the book included sections about Star Wars Rebels, A New Hope, The Empire Strikes Back, and a little foray into Return of the Jedi. The sections on Rebels were a welcome return to my favorite new subject matter, after writing Star Wars Rebels: The Visual Guide. Ultimate Star Wars builds on that book and was expanded to cover material from the entire first season of Rebels.
