Vector Prime
Robert Anthony Salvatore
 The alien race known as the Yuuzhan Vong are preparing for their invasion on the Star Wars galaxy. They are doing this by covertly disrupting the peace established by that of the New Republic ever since the fall of the Galactic Empire years previously. These distractions allow for the specialist warrior caste, the Praetorite Vong, to establish a base on the frozen backwater world of Helska IV. But though they settle on Helska IV as secretly as possible, it is noticed nevertheless by the members of the ExGal-4 base on the nearby world of Belkaden, which is also infiltrated by a Yuuzhan Vong agent named Yomin Carr. Three ExGal-4 members go to Helska IV to investigate what is happening, and two of the members are killed by the Praetorite Vong, while the remaining one, Danni Quee, is captured and tortured for experimentation. Back on Belkaden, Yomin Carr readies the planet for Vong habitation by poisoning the world as the initial step in terraforming and he kills the remaining Ex-Gal-4 scientists personally. Meanwhile, the Skywalker-Solo family, who, like the New Republic, are unaware of the Yuuzhan Vong threat, decide to take a vacation from the bureaucratic troubles of the Republic and go visit Lando Calrissian at his industrious planet of Dubrillion. There, they see the liftoff of Jedi Master Kyp Durron's Dozen-and-Two Avengers X-wing squadron, whose sole purpose is to protect the galaxy from criminal and pirates. Lando, meanwhile, asks Luke Skywalker and his wife Mara to go and investigate what is happening on the world of Belkaden with R2-D2. They go, and Mara gets into a fight with Yomin Carr that she wins by killing him. This is despite her sickness that, incidentally, the Yuuzhan Vong had given her through their agent, Nom Anor. Lando also asks Han Solo, his son Anakin, and Chewbacca to go to the planet Sernpidal to pick up some cargo. They comply, but as they arrive, they find that the Praetorite Vong have decided to make a target of the planet by pulling its moon, Dobido, down. Meanwhile, at Helska IV, the Dozen-and-Two Avengers get into a battle with the Praetorite Vong, which marks the first-ever battle in the Yuuzhan Vong War, and the squadron is easily decimated under the mighty forces of the Vong. Kyp Durron and his apprentice, Miko Reglia, are the only survivors, but while Kyp is able to escape to tell the rest of the galaxy of this new threat, Reglia is taken captive and tortured like Danni Quee. Helska IV would later be raided and investigated again by the Skywalkers after they leave Belkaden. Back at Sernpidal, Han, Chewbacca, and Anakin save as many people as they can aboard the Millennium Falcon, but unfortunately, Chewbacca is incidentally left behind and dies as Dobido crashes into Sernpidal, destroying the world. As the Solos and Skywalkers fall into grief over Chewbacca's death, they and their allies also find themselves facing the threat of the Yuuzhan Vong. The final battle against the Praetorite Vong occurs when Jacen Solo senses a call in the Force by Danni Quee, so he takes his sister, Jaina, with him to rescue her covertly. Their cover is soon blown, but they are then quickly aided with forces from the New Republic that battle off the Vong and manage to get Jacen and Danni off of Helska IV. Miko Reglia, unfortunately, sacrifices himself against a few Vong warriors to make sure that Jacen and Danni escape. With Jacen and Danni returned, the New Republic makes a quick plan to destroy Helska IV by using heat-concentrating ships to blow the world up. The vast majority of the Praetorite Vong are destroyed in this explosion, and it appears that the New Republic has beaten this alien menace. However, it turns out that the actual Yuuzhan Vong invasion force have yet to make any real appearance in the galaxy. The novel ends with the Skywalkers and Solos returning to Sernpidal so that Han can say a few words about Chewbacca in the wake of his sacrifice. He concludes that with his death, the galaxy has become a more dangerous place than ever.
