Disclaimer: I listened to the Thrawn: Alliances audiobook, as narrated by Marc Thompson.
Timothy Zahn’s original Thrawn trilogy was the first work of science fiction I ever read… in so far as any Star Wars product can be called sci-fi. When Zahn returned to his arguably most popular character, introducing him to Marvel’s newly retconned continuity. I was truly and well excited about the possibilities, and 2017’s Thrawn did not disappoint. It introduced the Grand Admiral, told the story of his rise to power in the Empire, and offered the reader a look at Coruscant during the Empire’s heyday.
LOST STARS by Claudia Gray is probably one of my top five Star Wars books with the others being THE THRAWN TRILOGY by Timothy Zahn and SHATTERPOINT by Matthew Stover. It is a book which doesn't talk about Luke Skywalker, Princess Leia, Han, or the other characters but follows two original characters through the events of the Galactic Civil War (A New Hope to the Battle of Jakku following Return of the Jedi).
