Tyrant’s Test is the final book in the Black Fleet Crisis trilogy. The novel builds on the separate stories of Han, Leia, and Luke that were established in the first two books of the trilogy. Leia faces political threats while trying to deal with the imminent war, which Han and Luke find themselves in the middle of.
Tyrant’s Test also sees the entrance of Chewbacca into the conflict, bringing in another classic Star Wars hero. It is a fitting end to a trilogy full of politics and intrigue, and continues to help build the story of the New Republic and the threats that it faces.
Faced with an alarming image of Han as a battered hostage of the Yevetha, Chewbacca takes on an urgent mission. Meanwhile, Leia calls upon the Senate to take a stand and eliminate the Yevetha threat, even at the cost of Han's life. As a former Imperial governor takes his battle to the runaway Qella spaceship, Luke's continuing search for his mother brings him dangerously close to Nil Spaar's deadly forces. And as the Yevetha close in on the forces of the New Republic, Luke takes a desperate gamble with an invisible weapon.
