Is the third trade paperback of the Marvel canon comic book series Star Wars: The High Republic.
The history-making saga of the High Republic era continues! With the stakes higher than ever before and time running out quickly, the Jedi must mount a daring rescue! The Nihil base is square in their sights — and Sskeer insists on going with them, no matter his condition. But a floating fortress at the heart of No Space [sic] will not be an easy target — will the best plan be a full-on attack, or an undercover infiltration? The way of the Jedi allows only one answer. Let battle commence...and may the Force be with our heroes!
